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

Can anyone please help me what is x<br>​
Masja [62]

Step-by-step explanation:

the side on the left of 155 is 180-155 which is 25

the one on top of 120 is 180-120 which is 60 so the one on the right of x is 180-(25+60) which is 95

now the value of x is 180-95 which is 85.

in the second one x=180-100 because the angle on the bottom of x is corresponding to the one that's equal to 100, so x=180-100 which is 80

for the first one x=85

the second one x=80
