Answer:
Step-by-step explanation:
hello :
cos²θ +sin²θ = 1 and cosθ =4/5
(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25
sin²θ = 9/25 = (3/5)²
sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

Answer:
yes, i agree. the right angle is 90 and 90+90=180. The law of the congruent angle states that if one angle in a the plane is right then the other connected must be as well, making line L 180.

i badly explained it however you should get the answer correct with that. i think... use your brain in addition to mine.
Answer:
1/3
Step-by-step explanation:
4/5 + 3/15
We first find a common denominator which will be 15.
Multiplying the top and bottom of 4/5, we have 12/15
12/15 + 3/15 = 15/15 = 1
1 - 2/3 is 1/3
