What is the value of angle 2x + 1 ? A.41 B.50 C.60 D.25<br><br>What is the value for x?
guajiro [1.7K]

Answer:

41

Step-by-step explanation:

These angles are vertical angles, and vertical angles are equal

2x+1 = 7x-99

Subtract 2x from each side

2x+1-2x = 7x-2x-99

1 = 5x-99

Add 99 to each side

1+99 = 5x-99+99

100 = 5x

Divide each side by

100/5 = 5x/5

20 =x

The 2x+1 angle equals

2(20)+1

40+1

Please answer this multiple choice question for 27 points and brainliest!!
storchak [24]

Answer:

A

Step-by-step explanation:

The equation will be in the form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line

m = \frac{0-5}{2.5-0} = - 2

The line crosses the y- axis at (0, 5) ⇒ c = 5

y = - 2x + 5 or

y = 5 - 2x → A

64 = r²

r = 8

d = 2(8)

d = 16
