Answer:
Side x is adjacent to 30° angle.
<u>Correct method is:</u>
- cos 30° = x/15 ⇒ x = 15*cos 30° ⇒ x = 12.99
Diego is correct and Steven is wrong.
- when finding <u>sine</u> consider the <u>opposite side to the angle</u>, not hypotenuse
- when finding <u>cosine</u> consider <u>adjacent side to the angle,</u> not hypotenuse

Answer:
-8
Step-by-step explanation:
if you sub in 8 as the value for y, you get
-4x - 8 = 24
add 8 on both sides to simplify
-4x = 32
divide both sides by -4
x = -8
Answer:
part A= x=1
part B= -13=-11 and -7=-7 and -2=-2
Step-by-step explanation:
part A
5+x-12=x-7
-7+x=x-7
x=1
part B
5+(-4)-12=-4-7
-1-12=-4-7
-13=-4-7
-13=-11
5+x-12=x-7
5+(-12)=-7
-7=-7
5+x-12=x-7
5+5-12=5-7
10-12=-2
-2=-2
