Angles y and z are complimentary. If angle y is 18°, what is the measure of angle z? 18°

36°

72°

162°

z = 72°

Step-by-step explanation:

Complimentary angles sum to 90° , thus

z + y = 180, that is

z + 18 = 90 ( subtract 18 from both sides )

z = 72°

So the right answer is 72 degree.

Good luck on your assignment

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
