question 5,6 who will answer will be mark as brainliest

Answer 1

Hi mate,
For 6)
As the sum of all the interior angles of triangle is 180
And angle on a straight line=180
130+x=180
x=50
80+50+y=180
130+y=180
y=50.
For 5)
As it is an isoceles triangle...
<x=<y
So we can suppose it as both as x
x+x+30=180
2x=150
x=75
y=75(as it is an isoceles triangle)
Hope it helps you my friend...
Please mark it as brainliest.....

Answer 2

if two side are equal of triangle then the angles opposite to them are als equal
hence angle ABC and angle ACB are equal
sum of angles of triangle =180=angle A+angle B+ angle C
=30+2angle B........angle B= C
180= 2 angle B +30
2 angle B = 180-30
angle B= 150/2
=75
angle B + angle x =180 ..... supplementry
angle x= 180-75
= 105
angle y = 105. .... by same method
