The solution is: the value of the angles a, b and c are : a = 60, b = 90, c = 100.
Here,
We have that in line CHF, it has two given and one unknown angle.
The total angle of one straight line is 180.
Given that:
a = 180 - 50 -70 = 60
The angle intersecting the CHFD line can be computed by the the total angle inside the triangle.
Angle on EFH would give 180-40-60 = 80 and on EFD the angle would be 100 from 180-80.
Since angle C is congruent to the angle EFD.
c = 100
Take note that in a 4 sided polygon (GEFH), the total exterior angle is 360 degrees.
The different angle would be
angle GHF = 50 + a = 50+60 = 110
angle EFH = 80
angle FEG = 180- c = 180-100 = 80
ANGLE EGH = 360 - GHF -EFH -FEG = 360 - 110-80-80 = 90
since angle AG is congruent to EGH, we can calculate for the angle b which is congruent to its opposite. This would give us formula of
360 = (90+90) + (b) +(b)
360 = 180 +2b
b = 90
Hence, The solution is: the value of the angles a, b and c are : a = 60, b = 90, c = 100.

Step-by-step explanation:
Linear equation that best describes the given model
Let
x ---> number of hours students spent studying
y ---> their score on the test
Looking at the line that was fit to the data to model the relationship
The slope is positive
The y-intercept is the point (0,45)
For x=1, y=55 ----> point (1,55)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the points (0,45) and (1,55)
Find the equation of the line in slope intercept form

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
6 x 4 =( x 4) + (3 x 4)
Now, split 6 as two equal quantities
6 = 3+ 3
So, 6 x 4 =24
( 3x 4) + (3 x 4)
= 12+ 12
= 24

r² = 204
r = 14.28 ft
Now

The second derivative of the function f is given by f" (x) = sin(x^2/8)-2 cos x. The function f has
many critical points, two of which are at x = 0 and x= 6.949. Which of the following statements is
true?
Answers
The answer choice which is true about the function f as described in the task content is; Choice D; f has a local maximum at x=0 and at x=6.949.
Which answer choice represents a true statement about function f?Since the equation which represents the second derivative of the function f is given; we have that;
By evaluating f'' (x) at each of the given values of x; we have that;
f'' (0) = sin ( 0² / 8 ) - 2 cos (0) = 0 - 2 (1) = -2
f'' (6.949) = sin ( 6.949² / 8 ) - 2 cos (6.949)
f'' (6.949) = -1.880.
On this note; since -1.880 < 0 and also, -2 < 0; it follows that the function f has a local maximum at x = 0 and x = 6.949.
Complete question includes answer choices;
a) f has a local minimum at x=0 and at x=6.949.
b) f has a local minimum at x=0 and a local maximum at x=6.949.
c) f has a local maximum at x=0 and a local minimum at x=6.949.

Hi!
So, first, let's just form the equation:
We know that all the side lengths equal 12 cm.
So the equation will be:
5 + 3 + x = 12
The answer you put in the box is:
5 + 3 + x
To find the value of x, we just solve this equation:
5 + 3 + x = 12
Combine like terms:
8 + x = 12
Same to both sides:
x = 12 - 8
x = 4

Find an equation of the line with the slope m=−1/8 that passes through the point (−5,0). Write the equation in the form Ax+By=C.
Answers
Answer:
x+8y= -5
Step-by-step explanation:
1) the required equation of the line has an slope-interception form:
y=mx+i, where m - slope, i - interception.
2) if the given point belongs to the required line, then it is possible to substitute its coordinates into the equation, then:
0=m*(-5)+i; ⇔-5m+i=0;
3) if the slope m= -1/8, then
-5*(-1/8)+i=0, ⇒5/8+i=0; ⇒ i= -5/8.
4) finally, the required equation is (m= -1/8; i= -5/8):
y= (-1/8)*x-5/8; ⇔ x+8y= -5.
