Question

PLEASE HELP ME! can someone explain this to me pls?​

Answer 1

Pythagorean theorem: a2 + b2 = c2

(5)^2 + b2 = (6)^2
25 + b2 = 36
-25. -25

b2 = 11
square root both sides to cancel out

and then label the missing side on the triangle = √11

and then point to the theta symbol and find sin, cos, tan, csc, sec, and cot

for example: sin (opposite/hypotenuse) = √11 /6
