For the first one, I cannot see what it is, it's blurry. But angle J= angle L

and angle K will be 180- 2 times angle L

bcs it's isosceles?

For the second one, both angles C and E will be the same.

For the third one, can't tell what angles x and z's values are, but they look the same.

If two angle values are the same in a triangle, it's isosceles, so 180-(x+z) will get you your answer

For four, blurry. BUT IT'S ISOSCELES INNIT? (you can tell by the little lines on the sides that tell u they are the same) so the two values at the bottom are the same. Do 180 minus them both.

For five,

4x + 7 = 9x - 33

take away 7 from both sides

4x = 9x - 26

then take away 4x

0=5x-26

For question six, can't see.

For seven, ISOSCELES

so that tells you

9x - 73 = 3x + 23

add 73 to make -73 not minus anymore

9x = 3x + 96

the rest is simple algebra>:)
