Answer:

x = 42 - 4

x = 38

Step-by-step explanation:

Given that :

Initial number of plane models = x

Number of additional models built = 4

Total number of planes = 42

Total = initial amount + additional amount

42 = x + 4

Make x the subject

42 - 4 = x + 4 - 4

x = 42 - 4

X + 4 = 42

X = 42 - 4

X = 38

Find the value of each variable and the measure of each labeled angle.
labwork [276]

Answer:

see explanation

Step-by-step explanation:

(8x - 75) and (5x) are vertically opposite angles and are congruent , then

8x - 75 = 5x ( subtract 5x from both sides )

3x - 75 = 0 ( add 75 to both sides )

3x = 75 ( divide both sides by 3 )

x = 25

Then

5x = 5(25) = 125°

8x - 75 = 8(25) - 75 = 200 - 75 = 125°
