Mathematics

trasher [3.6K]2 years ago
4 0
X^2 + 20x + 13 = 0
x^2 + 20x = -13

(B/2)^2 = (20/2)^2 = 10^2 = 100

x^2 + 20x + 100 = -13 + 100

(x + 10)^2 = 87

Given that sinθ=8/17 , what is cosθ ? Enter your answer, as a simplified fraction, in the boxes.
leonid [27]

Cosθ = 15/17

Step-by-step explanation:

Sinθ = 8/17

We know that,

Sin^2 θ + cos^2 θ =1

64/289 + cos^2 θ =1

1 - 64/289 = cos^2 θ

225/289 = cos^2 θ

Cos θ = √225/289

Cos θ = 15/17
