Find the value of x. if necessary, round to the nearest tenth. a) 8.9 in. b) 10.8 in. c) 12.6 in. d) 6.3 in.

a) 8.9 in.

Step-by-step explanation:

From the given picture it can be seen that the area of the triangle A = 40 sq. in.

The height of triangle = base of the triangle =x

We know that the area of triangle is given by :-

Hence, the value of x = 8.9 in.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
