Area of triangles: 1/2 x b x h
area of square: l x w

Triangle
1/2 x 7 x 4= 14, but there are 3 of them so 42
Square: 7 x7 = 49

49 + 42 = 91

Answer:

120°

Step-by-step explanation:

I drew a picture that will make it easier to understand what's going on. Please see the attached image

In a rhombus, the diagonals bisect the opposite angles, and opposite angles are congruent.

Let's say angle 1 is x. The interior angles of a quadrilateral add up to 360°, so

30+30+30+30+2x=360

2x=240

x=120

angle 1 is 120°.
