Answer:

If you're rounding to the nearest 10th, the answer is 9.9.

Step-by-step explanation:

I solved it using the pythagoras theorem.

Where c = the square root of a^2 (a squared) plus b^2 (b squared).

(x = c in this case).

Since this is an isosceles triangle sides a and b both equal 7.

Hope this helped!

Answer:

Step-by-step explanation:

From the Pythagorean Theorem we know

h^2=a^2+b^2 (where h is the hypotenuse of a right triangle and a and b are its legs)

In this case the single tick marks on the legs indicate they are the same length then

h^2=a^2+b^2 becomes

h^2=2a^2, and a=7 so

h^2=2(7^2)

h=7(2^(1/2))

h=9.9

x=9.9 (to nearest tenth)
