2A) first find the measure of the angle above the right angle (180-122=58) so it equals 58°, while the right angle is obviously 90°. the whole triangle should be 180° so 90+58= 148. now we subtract this from 180 to get the measure for x. 180-148=32.
Therefore, x=32°
Answer:
30 cm²
Step-by-step explanation:
we need to find h
V=πr²h
h=V/πr²
h=210/14²π
h=0.341
then we found curved surface area
A=2πrh
A=2×π×14×0.341
curved surface are= 30 cm²
