Question

A= 40sq. in.

Find the value of x. If necessary, round to the nearest tenth.

Answer 1

Answer:

8.9 inches

Step-by-step explanation:

Area of a triangle is equal to base times height divided by 2.

$bh/2$

Base and height is x.

$xx/2=40$

Solve for x.

$x^2=40 \times 2$

$x^2=80$

$x=\sqrt{80}$

$x=8.944272$

Answer 2

Answer:

Just like in the other question, we can write:

40 = x * x / 2

40 = x² / 2

x² = 80

x = ±√80 → √80 → 8.9
