Answer:
<h3>83°</h3>
Step-by-step explanation:
Given the parameters
m2 ROC = 31° and
m2 COL = 52°
According to the diagram in the attachment;
m2 ROL = m2 ROC + m2 COL
Substitute the given values into the expression as shown;
m2 ROL= 31°+52°
m2 ROL = 83°
Answer:
UV=142
Step-by-step explanation:
21x-13=10x+31
+13 +13
21x=10x+44
-10x=-10x
11x=44
÷11 ÷11
x=4
now substitute 4 in place of x (only have to solve one)
21(4)-13= 71
now multiply your answer by 2
71×2=142
