Answer:
A
Step-by-step explanation:
Since cosine is positive and sine is negative that puts θ in Quad IV.
From right triangles we know:
Cos θ = adjacent/hypotenuse = 5/13
sin θ = opposite/hypotenuse = ?/13
To find the opposite side across from θ use the pythagorean theorem.
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
we are given that sin is < 0 so sinθ = -12/13
Answer:
59-12 would be 47 points and by all means you would have an F
Step-by-step explanation:
59-12=47
Solution:
we have been asked to find the true statement about the exterior angle from the given statements.
As we know that the exterior angles are always out of the triangle and it makes a sum of 180 with anyone of the internal angle of the triangle.
The pair lies on the same straight line and makes a pair.
Hence we can say that it is formed by a linear pair with one of the interior angles of the triangle.
Hence the correct option is D.
