73.5
Answer:
y=−2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6y+2(3y−5)=−34
6y+(2)(3y)+(2)(−5)=−34(Distribute)
6y+6y+−10=−34
(6y+6y)+(−10)=−34(Combine Like Terms)
12y+−10=−34
12y−10=−34
Step 2: Add 10 to both sides.
12y−10+10=−34+10
12y=−24
Step 3: Divide both sides by 12.
= 
y=−2
When we need the cosine of the sum of two angles, we use the addition formula for cosine.
When we need the sine of the difference of two angles, we use the difference formula for sine.
Let's try one. Say we needed to know

We're only expected to know the trig functions of 30/60/90 and 45/45/90 triangles. Fortunately,

so
