One side of triangle is given equilateral triangle which means all the angles of the triangle is 60°
so we have angles of bigger triangle:-
- 60°
- 60+35= 95°
- x( to find )
<h3>Use angle sum property </h3>
( sum of all interior angles is 180°)

Answer:
(b) Ingrid’s claim is correct, but her steps are incorrect
Step-by-step explanation:
As nearly as we can tell from the problem statement, Ingrid's table looks like the one attache. We have highlighted the incorrect steps.
Step 3 should read ...
0·cos(y) -(-1)·sin(y) = sin(y) . . . . . . . . . sin(-π/2) = -1
Step 4 should read ...
0 + sin(y) = sin(y)
So, Ingrid's conclusion is correct, but her steps are incorrect.
