Can the measure of an exterior angle of a triangle ever exceed 180°? Explain your reasoning.
Answers
Answer:
Yes I believe so because the interiors of a triangle always add up to 180 degrees meaning the outside mustn't follow this same rule hop this helps!
Step-by-step explanation:
Answer:
Lets assume you have a triangle ABC with a straight horizontal line at the bottom say line segment CD. In order for the exterior angle to be greater than 180 it must be a exceed rad Pi which mean it is impossible for an exterior angle to exceed the 180 rule

A 25 foot ladder is leaning against a house. If the angle of Elevation of the ladder is 72 degrees:
How high up the house does the ladder touch?
How far away is the ladder from the house?
Round to the nearest tenth.
Answers
Answer:
1. 23.8
2. 7.7
Step-by-step explanation:
for the first blank
use sin because x is opposite and 25 is hypotenuse
set up an equation:
sin(72)= (x/25)
multiply both sides by 25:
25(sin(72))= (x/25)25
25(sin(72))= x
multiply 25 by sin(72):
23.8 = x
for the second blank
use cos because x is adjacent and 25 us hypotenuse
set up an equation:
cos(72)= (x/25)
multiply both sides by 25:
25(cos(72))= (x/25)25
25(cos(72))= x
multiply 25 by cos(72):
7.7= x

A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?
Answers
Answer:
289300 miles/72 hours * 1.60934 km/mile* 1 hour/3600 seconds = 1.48 km/second. Answer 6: To get average speed, we divide the total distance by the total time it takes to travel that distance. If we assume the distance to the moon is 238,900 miles then we divide by 72 hours to get roughly 3318 mph.

Use the Pythagorean theorem to obtain the function D(x) for the length of the diagonal of a double square of width x.
Answers
Answer:
[tex]D(x)= x\sqrt{2}[/tex]
Step-by-step explanation:
Given
[tex]Side = x[/tex]
Required
Represent the diagonal as a function
Using Pythagoras theorem, the diagonal is:
[tex]D^2= Side^2 + Side^2[/tex]
Substitute x for Side
[tex]D^2= x^2 + x^2[/tex]
[tex]D^2= 2x^2[/tex]
Take the square root of both sides
[tex]D= \sqrt{2x^2[/tex]
Split
[tex]D= \sqrt{2} * \sqrt{x^2[/tex]
[tex]D= \sqrt{2} * x[/tex]
[tex]D= x\sqrt{2}[/tex]
Express as a function.

If you can help me with Slope Intercept plz help me
Answers
Answer:
y = 6/5x - 2 (or y = 1.2x - 2)
Step-by-step explanation:
To find the slope-intercept form ( = mx + b) you need to rearrange the equation of the line:
Step 1 - Add 18x to both sides
15y = 18x - 30
Step 2 - Divide both sides by 15.
y = 6/5x - 2

(7,2) and has a slope of
1
1?
Answers
Answer:
(y+2)= -3(x-7)
Step-by-step explanation:
We can use the slope-intercept formula to write this equation. The slope-intercept form of a linear equation is:
y = m x + b
Where m is the slope and b is the y-intercept value.
We can substitute the slope into the formula giving:
y = − 3 x + b
Next, we can substitute the values from the points in the problem for x and y and solve for b :
− 2 = ( − 3x 7 ) + b
− 2 = − 21 + b
21 − 2 = 21 − 21 + b
19 = 0 + b
19 = b
We can now substitute the slope from the problem and the value for b we calculated into the formula to write the equation.
y = − 3 x + 19
Another process is to use the point-slope formula. The point-slope formula states:
( y − y 1 ) = m ( x − x 1 )
Where m is the slope and ( x 1 , y1 ) is a point the line passes through.
Substituting the slope and values from the points in the problem gives:
(y − − 2 ) = − 3 (x-7)
( y + 2 ) = − 3 ( x − 7 )

1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?
Answers
Answer:
Step-by-step explanation:
Given that:
Each small square on a grid represents 1 unit
Base of triangle = 5 1/2 units = 11/2
Area of triangle = 19 1/4 unit² = 77/4
The Area, A of a triangle is obtained thus :
77/4 = 1/2 * 11/2 * h
77/4 = 11/4 * h
h = 77/4 ÷ 11/4
h = 77/4 * 4 /11
h = 7 units

A postcard has a perimeter of 20 inches. Its area is 21 square inches. What are the dimensions of the postcard?
Answers
Answer:
Length = 3 inches
Width = 7 Inches
Step-by-step explanation:
The shape of a postcard = Rectangle
L = Length
W = Width
A postcard has a perimeter of 20 inches.
Formula for perimeter of a rectangle = 2L + 2W
Hence:
2L + 2W = 20.... Equation 1
Its area is 21 square inches.
The formula for Area of a rectangle = LW
Hence:
LW = 21
L = 21/W
We substitute 21/W for L in Equation 1
2L + 2W = 20.... Equation 1
2(21/W) + 2W = 20
42/W + 2W = 20
Multiply both sides by W
42 + 2W² = 20W
2W² - 20W + 42 = 0
2W - 14W - 6W + 42 = 0
(2W - 6)( W - 7) = 0
2W - 6 = 0
2W = 6
W = 6/2 = 3
W - 7 = 0
W = 7 inches
Solving for L
L = 21/W
W = 7
L = 21/7
L = 3 inches
The dimensions of the postcard are:
Length = 3 inches
Width = 7 Inches
