Question

I NEED HELP ASAP!What is the area of the triangle shown below? 10 10 12​

Answer 1

Answer:  48 square units

=============================================================

Explanation:

Draw a vertical line to cut the triangle into two equal parts. You'll get two right triangles.

The horizontal leg of one of those smaller triangles is 12/2 = 6 units. The hypotenuse is 10 units. Through the pythagorean theorem, you should find the vertical leg is 8 units.

We have a 6-8-10 right triangle.

The area of this smaller triangle is base*height/2 = 6*8/2 = 48/2 = 24 square units.

So the area of the larger triangle is 2*24 = 48 square units.

Answer 2

Answer:

$h^2+6^2=10^2$

$h^2+36=100$

$h^2=100-36$

$h^2=64$

$h=8$

$A=1/2 ~BH$

$A=1/2(12)(8)$

$A=48 ~units^2$

hope it helps...

have a great day!!
