Step-by-step explanation:
I didn't need the other angles, but right of the bat you can tell it's two right triangles back to back.
<em>y </em> has to be 90° , as you have noticed they already gave you 70° on the right side of the shape meaning if you were to add 90 which is why plus 70 what would that give you? 160.
the total interior for a triangles angles has to be 180°. if you do the math 180 - 160 you get the leftover 20° for x.
I suck at explaining stuff, hope this helps
The area of the composite shape is the sum of the area of the triangle and the area of the rectangle. The area of the composite shape is 53 in².
<h3>What is Geometry?</h3>It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The composite is made up of triangles and rectangles.
The area of the composite shape will be the sum of the area of the triangle and the area of the rectangle.
The area of the triangle will be
The area of the rectangle will be
The area of the composite shape is 48 + 5 = 53.
The area of the composite shape is 53 in².
