<span>If you pull the edges of the right angle down it makes a straight line.
Therefore, the angles in a triangle add up to 180°
So, 35 + 45 = 80
Then, 180 - 80 = 100
The third angle = 100° </span>
Answer:
B, D
Step-by-step explanation:
These are the correct answers.
Answer:
x = 2√5 and x = - 2√5
Step-by-step explanation:
x^2 = 20
x = 2√5 and x = - 2√5
4-3x=o (o being egg orders)
2x+6=w (w being waffle orders)
Expand
13x - 16 - 10x = 12 - 11x
Simplify 13x - 16 - 10x to 3x - 16
3x - 16 = 12 - 11x
Add 16 to both sides
3x = 12 - 11x + 16
Simplify 12 - 11x + 16 to -11x + 28
3x = -11x + 28
Add 11x to both sides
3x + 11x = 28
Simplify 3x + 11x to 14x
14x = 28
Divide both sides by 14
x = 28/14
Simplify 28/14 to 2
x = 2
