Answer:

Step-by-step explanation:
Given

Solve:

Simplify 6/10

Express 9 as 3^2

Apply law of indices


Express as a sing;e fraction

Apply law of indices:




Angle on a straight line sums up to 180
so
72+x + x+130 = 180
2x = 180-72-130
2x =-22
x= -11
so Angle on the LHS is 61°
while angle on the RHS is 119°
