Can someone please help me?? trying to retake some questions If angle U = 8x + 9 degrees, and angle W = 8x - 5 degrees, then the measure of angle U is ___ degrees.

97 degrees

Step-by-step explanation:

We know that U and W add up to 180 degrees so we can write:

8x+9+8x-5=180

Simplify:

16x+4=180

We can figure out x from here!

x=11

Since x=11, we can plug that in and get:

88+9=97

im not sure

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

the answers might not be correct use at own risk
