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)
