Answers: Angle A is 36 degrees, angle C is 54 degrees
=================================================================
Work Shown:
The angles A and C are complementary, meaning they add to 90 degrees.
(Angle A) + (Angle C) = 90
(2x-4) + (2x+14) = 90
(2x+2x)+(-4+14) = 90
4x+10 = 90
4x+10-10 = 90-10 .... subtract 10 from both sides
4x = 80
4x/4 = 80/4 ..... divide both sides by 4
x = 20
If x = 20, then,
angle A = 2x-4 = 2*20-4 = 40-4 = 36 degrees
angle C = 2x+14 = 2*20+14 = 40+14 = 54 degrees
Note how A+C = 36+54 = 90 which helps confirm our answers.
Answer: 1mi/5280
Step-by-step explanation: I dunno how to explain this. Its really easy. Always have the converting unit on the denominator
Answer:
X= 20
Step-by-step explanation:
Since the they are both interior angles they can be set equal to each other.
The answer would be 10.51
Answer:
x=7
Step-by-step explanation:
6-6x=5x-9x-8
Combine like terms
6-6x=-4x-8
Add 6x to each side
6-6x+6xx = -4x-8+6x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 =2x/2
7 = x
