Question

who ever answered he or she/is god or genies.....really....

Answer 1

1
sum of triangle=180°
so angleA +angleB+angleC=180
angleC=180-135
=45°answer
2.same as first
180-145
angleD=34
3.same as third
180-138
42°ans
4.let the angle be x
so 4x+3x+2x=180
9x=180
x=20
4x=4×20=80°
3x=3×20=60°
2x=2×20=40°
5.
in this one is 90°
and second is 36°
find another
so
180-126
54°
6. let two angle be x
so 90+2x+x=180
3x=90
x=30
so one angle 2×30 =60
and Another is 30
7. let another be x
same as 6 question
100+x+x=180
2x=80
x=40 answer
