8. In AABC, mC = 90° and sin A = What is m angle B in degrees?
A. 30°
B. 45°
C. 60°
D. There is not enough information to determine.

C

Step-by-step explanation:

The degrees of a triangle add up to 180.

Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.

Angle A is equal to sinA=1/2.

sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.

90-30=60.

That leaves you with 60 degrees for angle B.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
