Question

please choose the correct answer, i will upvote all your comments! look at triangle stu: a right triangle stu is shown with the right angle at t. the length of side st is labeled as 42 cm, and the length of side tu is labeled as 56 cm. what is the length (in centimeters) of side su of the triangle? 70 centimeters 77 centimeters 90 centimeters 98 centimeters

Answer 1

Took the test it’s 70. Centimeters

Explanation:

Answer 2

Since this is a right triangle, we can just use Pythagorean Theorem to solve for the side SU:

Length of Hypotenuse^2 = Length of First Leg^2 + Length of Second Leg^2
SU^2 = ST^2 + TU^2
SU = sqrt(ST^2 + TU^2)
SU = sqrt(42^2 + 56^2)
SU = sqrt(4900)
SU = 70

Therefore, the answer is is 70 centimeters.
