Step-by-step explanation:


<em>Thus, the expressions will be used: (5x² + 15x - 20) and (x + 4).</em>
<em>Let's check:</em>

Answer:
21.8
Step-by-step explanation:
Answer:
m<U = 
Step-by-step explanation:
From the given question, it can be observed that angles U and W are supplementary. These are angles that add up to
.
So that;
<U + <W = 
(8x + 9) + (8x - 5) = 
16x + 4 = 
16x =
- 4
16 x = 176
x = 
= 
The measure of angle U = (8x + 9)
= 8(11) + 9
= 88 + 9
= 
Thus, the measure of angle U is
.
I don’t know the answer, but when you get it can you tell me I have a similar problem on my test
It needs only one 360 degree angle to make a full turn
It is also known as an angle at a point ..
