Please help I’m not sure how u solve for an isosceles triangle

Solve for x

Step-by-step explanation:

Pythagorean theorem. (Root 80 ^ 2) - (8^2) = (80) - (64) = 16 Root16 = 4 and since the bottom angles are the same you just multiply your Answer by two to get x. So x=8

The answer to your question is x = 8

Step-by-step explanation:

Data

Isosceles triangle

side 1 = √80

height = 8

x = ?

Process

To solve this problem, divide the triangle in two equal triangles and find x/2 using the Pythagorean theorem.

1.- Calculate x/2 (m)

hypotenuse = √80

long leg = 8

short leg = x/2 = m

                   (√80)² = 8² + (m)²

-Solve for x/2

                    80 = 64 + (m)²

                    80 - 64 = m²

                     m² = 16

                     m = √16

                     m = 4

2.- Find x

x = 2m

x = 2(4)

x = 8

just sum

10 + 10 = 20

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
