Equation with angles can someone please answer please help

The lines are parallel , so angle A and angle B form exterior alternate angles. Thus they are equal

Thus

Step-by-step explanation:

Parallel lines. Alternate exterior angles are equal

∠A  = ∠B

6x - 2 = 4x + 48

Add 2 to both sides

6x - 2 + 2 = 4x + 48 + 2

6x = 4x + 50

Subtract 4x from both the sides

6x - 4x = 4x + 50 - 4x

2x = 50

Divide both sides by 2

2x/2 = 50/2

x = 25

∠A = 6x - 2 = 6*25 - 2 = 150 - 2 = 148

∠A = 148°

the answer is d. 75%

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
