Answer:
b = 33.4
Explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
11.25 ^2 + b^2 = 35.25^2
125.5625 + b^2 = 1242.5625
125.5625-125.5625 + b^2 = 1242.5625-125.5625
b^2 = 1116
Take the square root of each side
sqrt(b^2) = sqrt(1116)
b =33.40658618
To the nearest tenth
b = 33.4
