Answer:
StartFraction 3 pi Over 10 EndFraction, 60°, StartFraction pi Over 2 EndFraction, StartFraction 2 pi Over 3 EndFraction, 255°
Step-by-step explanation:
you convert everything to degrees
using formula 180/pi,
for example pi/2 times 180/p=90 degrees
Answer:
Basically it has to pass through 2 (I think) and the y-intercept is -3
Step-by-step explanation:
Answer:
20°
Step-by-step explanation:
To find ∠C you don't even need 90° unless you would want to check if you are correct. to find ∠C you would just look for the whole triangle, so basically A + B + C = 180.
80 + 30 = 110
180 - 110 = 70
∠C = 70
Then you would take 70° and subtract it to 90° since it is a right angle combined with x and you would get your answer which is 20°.
