both are true

Step-by-step explanation:

(4)

Given

7(x + 2x) and 21x

Consider

7(x + 2x) = 7(3x) = 7 × 3x = 21x → True

(5)

Given

2a + 2b + 2c and 2(a + b + c)

Consider

2(a + b + c) ← multiply each term in the parenthesis by 2

= 2a + 2b + 2c → True

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: x=60
