1/4= 0.25 como un decimal
The question is a bit confusing can rephrase it?!
You have to change the denominator of 6/10 into 100 then you will get 60/100 then you add 15/10+60/100
-m-4=-13
-m=-13+4=-9
m=9

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
