Answer 1

Answer:

sin 70 degrees = 0.9396, 0.9396*3 approximately equal to the 2.82cm  one area is 6*2.82/2=8.46cm²

Step-by-step explanation:

1. Known this square covers an area of 36 cm square, so its length is 6 cm.
2. so, we know that the lower side of the triangle is six, half of it is 3 cm.
3. We make a triangle, and then the Angle of the triangle is 70 degrees, so, we can use the sin is to use bottom neighborhood is sin70 degrees = hemline is present in addition to 3cm.

Answer 2

Answer:

If the area of the square is 36 then a side length would be 6 the area of a triangle is 1/2b*h the base is 6 and the height is 6

So A=1/2B*H

A=1/2*6*6

A=18cm
