Answer 1

Answer:

11

Step-by-step explanation:

Answer 2

Answer:

third side = 11

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

third² + 60² = 61²

third² + 3600 = 3721 ( subtract 3600 from both sides )

third² = 121 ( take the square root of both sides )

third = [tex]\sqrt{121}[/tex] = 11

The third side is 11 units

What are the values of a and b, and what is an equation for the line?

Answers

Answer:

a = 1,  b = 6

Step-by-step explanation:

slope of line = (5-2) / (12-3) = 3/9 = 1/3

(3-2) / (b-3) = 1/3

b-3 = 3        b = 6

(2-a) / (3-0) = 1/3

2-a = 1          a = 1

For which value of m is start fraction 4 over 16 end frction equals start fraction m over 24 end fraction a proportion? A. m = 6 B. m = 8 C. m = 12 D. m = 14

Answers

Answer:

A. M=6

Step-by-step explanation:

Basically, this question is asking you to find m if 4/16 = m/24.

First, 4/16 can be simplified to 1/4. This will make it easier to solve.

You now have 1/4 = m/24.

Multiply both sides by 24 to get 24/4 = m.

Simplify to get m = 6.

In the triangle below, ∠Q is a right angle. Which ratio would be equivalent to the ratio of sin∠R?
a) cos∠Q
b) cos∠S
c) sin∠Q
d) sin∠S

Answers

Answer:

b) cos∠S

Step-by-step explanation:

sin ∠R = SQ/SR

This is same as:

cos S

Correct option is b)

cos<Q

Lets do

[tex]\\ \sf\longmapsto sin<R=\dfrac{P}{H}[/tex]

[tex]\\ \sf\longmapsto sin<R=\dfrac{SQ}{SR}[/tex]

Now

[tex]\\ \sf\longmapsto cos<Q=\dfrac{B}{H}[/tex]

[tex]\\ \sf\longmapsto cos<Q=\dfrac{SQ}{SR}[/tex]
