Question

10. Two angles form a linear pair. One angle measures (10x - 63)°. The other angle measures (8x)". What is the

value of x?
a 8.5
b. 31.5
c. 13.5
d. Cannot be determined

Answer 1

Explanation:

if the angles form a linear pair, that means their sum=180

10x-63+8x=180

18x=180+63

x=243/18=13.5 choice c
