Question

Find the value of X in the isosceles triangle shown below.

Answer 1

Answer:

D) Square root of 48

Step-by-step explanation:

We have to split the triangle in half and then multiply that by two for the answer. Then we use a²+b²=c² because the two triangles are right triangles, and we know b=4 and c=8, so a²+(4²)=8², or a²+16=64

a² would have to equal 48. a=√48.
