Answer:
Step-by-step explanation:
<u>Angle alpha is 16° greater than the angle beta:</u>
<u>Angle gamma is 52° smaller than the beta:</u>
<u>Sum of angles is 180°, substitute α and β:</u>
- α + β + γ = 180°
- β + 16° + β + β - 52° = 180°
- 3β - 36° = 180°
- 3β = 216°
- β = 216°/3
- β = 72°
<u>Then</u>
- α = 72° + 16° = 88°
- γ = 72° - 52° = 20°
Answer:
A) 22.5
Step-by-step explanation:
The product of the length of one secant segment and its external part is equal to the product of the length of the other secant segment and its external part.
(5+13)*5 = x*4
18*5 = 4x
90 = 4x
Divide each side by 4
90/4 =4x/4
22.5 =x
