Answer:
50°
Step-by-step explanation:
An inscribed angle is half the measure of its intercepted arc. Here, arc AC is ∠B's intercepting arc. Arc AC is 100°, and 100/2 = 50, so ∠B is 50°.
A=10ft because A is 8ft so round that to the nearest ten your answer is 10ft
So we need to solve:
3ˣ⁻¹ = 9ˣ⁺²
To do this, we need to have the same base for both sides of the equation.
So let's go with the base of 3.
3² = 9
3ˣ⁻¹ = (3²)ˣ⁺²
3ˣ⁻¹ = 3²ˣ⁺⁴
Since the bases are the same now, we need to get rid of them and we would get:
x - 1 = 2x + 4
Subtract both sides by 2x:
-x - 1 = 4
Add 1 to both sides:
-x = 5
Divide both sides by -1:
x = -5
