Hello!

When doing Sine, Cosine and Tangent the sides of the triangle tell you what to do

The hypotenuse is H
The bottom side is A
The Straight up and down side is O


For Sine you do O / H
For Cosine you do A / H
For Tangent you do O/ A

Put in the values you Sine

Sin A = 5/ 13

Put in the values for Cosine

Cos A = 12/ 13

The answer is A) Sin A = 5/ 13, cos A = 12/ 13

Hope this helps!

Solve the quadratic equation.<br> (a + 5)2 +36 = 9
Andrej [43]

Answer:

No solution unless you want to solve for an imaginary number which in that case a=27i-5

Step-by-step explanation:

(a+5)^{2} +36=9

(a+5)^2=-27

a+5=\sqrt{-27}

Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:

a+5=\sqrt{-1} \sqrt{27}

a+5=27i

a=27i-5
