Answer:
Angle X is 122°
Step-by-step explanation:
Because it's a 180° line (supplementary angle thm):
180°-58°=122°
Answer:
114°
Step-by-step explanation:
The measure of an arc is double the measure of the angle between the chord and the tangent line.
127=(120+7)
32=(30+2)
I hope its correct
Answer:
The height is 11/2
Step-by-step explanation:
We know SA = 30n
and r = 2
We are solving for h. So plug in our values
30n = 2n(2)^2 + 2n(2)h
Multiply and square on the right side terms
30n = 8n + 4nh
Divide everything by n
30 = 8 + 4h
Subtract 8 on both sides
22 = 4h
Divide by 4 on both sides
h = 22/4 = 11/2
Check:
30n = 2n(2)^2 + 2n(2)(11/2)
30n = 8n + 22n
30n = 30n
