Need help with an explanation please!! 15 points for whoever can help me

Answers

Answer 1

Answer: Because one angle is shared between the smaller and larger triangles, this angle is clearly equal. In addition, their sides surrounding that angle are in the same ratio, so these triangles are similar by SAS similarity, with a ratio of 2. This means the sides of the big triangle are twice as long as the ones of the small triangle. As a result, x is equal to 46*2=92.

Find the dimension of the triangle

Answers

Given:

The area of the triangle is 24 yd²

The height of the triangle is 4 yd.

We need to determine the base of the triangle.

Base of the triangle:

The base of the triangle can be determined using the formula,

$Area=(1)/(2)bh$

where b is the base and h is the height of the triangle.

Substituting $Area =24, h=4$ in the above formula, we have;

$24=(1)/(2)b(4)$

Simplifying, we get;

$24=2b$

$12=b$

Thus, the base of the triangle is 12 yard.

Hence, Option A is the correct answer.
