In ABC the measure of angle A is 2x+4 , the measure of angle B is 4x+2 , and the measure of angle C is 2x-1. What are the measur es of the angles?
2 answers:
A right angle is 90 degrees, so~ 2x+4 +2x-1+4x+2 = 90 (these are the angles' equations) Combine like terms 8x+5 =90 -5 -5 8x = 85 /8 /8 x=10.625BUT YOU AREN'T DONE YET ;D Plug in x and solve the equations. ~Hope this helps~
(2x+4)+(4x+2)+(2x-1)=180 8x+5=180° 8x=180-5 8x=175 X=21.875 A= 2(21.875)+4=47.75 B=4(21.875)+2 =89.5 C=2(21.875)-1=42.75
