Answer:

a)29

b)70

Step-by-step explanation:

The sum of the interior angles in a triangle is 180.

a)95+56+a=180        b)40+2b=180

151+a=180                     2b=180-40

a=180-151                      2b=140  /2

a=29                              b=70
Every angle in a circle must add to give 180 so therefore for the first question =
a) 95+56+__ = 180 so the answer would be 29
Isosceles triangles have two identical angles inside that need to be the same.
b) 180-40=140 and to have two identical angles half 140 which gives you a final answer of 70
