Answer:
x = 7 and the degree of other two angles is 69.
Step-by-step explanation:
As we can see it is an isosceles triangle so base angles of an isosceles triangle are equal so
9x + 6 + 9x + 6 + 42 = 180 (being sum of angles of triangle )
18x + 54 = 180
18x = 180 - 54
18x = 126
x = 126/18
x = 7
the degree of the other two angle is
= 9*7 + 6
= 69
Hope it helps :)
