Answer 1

Answer:

$\frac{ {3}^{11} }{ {3}^{3} }$

${3}^{11 - 3}$

${3}^{8}$

Answer 2

Solution

This is isosceles triangle so its two angle will always be equal

Thus, the other two interior angles are = 30⁰+2(unknown angles) =180⁰=>2 unknown angle = 180⁰-30⁰= 150

Unknown interior angle= 150/2 =75⁰

Exterior angle = 180⁰-75⁰= 105⁰

Also it is given that x=y

• Thus x= 105⁰ and y= 105⁰
