Answer:
35 degrees, 60 degrees, and 55 degrees
Step-by-step explanation:
I'm not sure what you're trying to ask for the answer, but I'm assuming it's the degrees.
Think about it: A right triangle automatically has a 90 degree angle, and it already gave one of the degrees as 35 degrees. Adding those up, it equals 125 degrees. 180 (sum of degrees in a triangle) -125=55 degrees.
Therefore, the triangle's degrees are 35, 55, and 60 degrees.

Answer:
a. Sin (θ) = 3 / 5
b. Cos (θ) = 4 / 5
c. Tan (θ) = 3 / 4
Step-by-step explanation:
a. Sin (θ) = 6 / 10 = 3 / 5
b. Cos (θ) = 8 / 10 = 4 / 5
c. Tan (θ) = 6 / 8 = 3 / 4
The answer is 16.25 adding all of those up
