Answer:
15
Step-by-step explanation:
Angle 2 is 2x+10
angle 4 is 4x+80
and from the figure we can understand that when we add these 2 equations
We get
6x+ 90= 180
6x = 180 - 90= 90
6x= 90
x = 90 ÷ 6 = 15
answer = 15
To find perpendicular lines you take a (-2), flip the number and the sign so that gets you 1/2. Then you check and keep doing 1/2 until you find the y int which is 0. The equation is y=1/2x+0 (you don't need the 0). Im pretty bad at explaining but the answer is correct.
Well you could say...... a girl had a bag of marbles then she spilt a 4th of her bag. After that her friend gave her 8 more marbles. Her final total is 10. How many did she start out with?
