Question

find the angles in the avove picture
​

Answer 1

Answer:

right angle, acute angle and obtuse angle.

Answer 2

Answer:

a) angle of interior angle is 360

so a+b+c+d=360

50+130+120+d=360

300+d=360

x=60

b) same in b) angle of all interior angle id 360

90+70+60+d=360

220+d=360

x=140

c) supplementary angle of base

180-70 = 110

180-60=120

angle of interior angle is 540

a+b+c+d+e=540

30+110+120+x+x=540

220+2x=540

2×=320

x=160
