Answer:
!%)O
Step-by-step explanation:
:)
The formula to find the area of a sector = Ф*r²/2
Ф to be in radian, here Ф=45° =π/4
sector = 1/2(π/4)x 100
sector = 39.27 ≈39.3° (B)
Answer:
a. Same Side Interior Angles
b. Corresponding Angle
c. Alternate Exterior Angle
d. Alternate Interior Angles
e. 20
f. 70
Step-by-step explanation:
e. Corresponding angle add up to 90 degrees. Which you have to subtract 110 to 90 and is 20
f. same side interior angle adds up to 180 degrees. Which you have to subtract 180 to 110 and it is 70
Well, since it is multiple choice, you can just eliminate the answers. If you take 5/4 it equals 1.25. Then you go through the choices. All of the numbers, except 7.2 (C) are infinite. And, 7.2 gives you the 1.25 from before... which is your answer
If this helped, brainliest would be great! Only need one more to level up :)
