Answer:
a.
b. x = 4 (see steps below)
Step-by-step explanation:
Since the two polygons are similar, the sides are proportional to each other. Using a proportion, you can solve for 'x' using cross-multiplication and division:
Cross-multiply: 15(x + 3) = 21(x + 1)
Distribute: 15x + 45 = 21x + 21
Subtract '15x' from both sides: 15x + 45 - 15x = 21x + 21 - 15x or 45 = 6x + 21
Subtract '21' from both sides: 45 - 21 = 6x + 21 - 21 or 24 = 6x
Divide by 6 on both sides: 24/6 = 6x/6
Solve for x: x = 4
Answer: 90°
Step-by-step explanation:
The two arcs made by the angle will add up to twice the value of the angle in degrees
89 * 2 = 178
178 - 88 = 90
Answer:
the exact form will be x = - , -
demical form is x=0.16148351....,-1.23851648
