Find the measure of 63°

on a number line or using a protractor to get 63 degrees u have to find wee the standard points are. like 90, 180, 260, 380 degrees. then use those to get closer.

Step-by-step explanation:

answer: i oofed

step-by-step explanation:

oofed=wow

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
