Step-by-step explanation:
Answer:
<5 is the remote interior angle to <1
They are on the same line, or, they are supplementary, and will add up to 180 degrees
Step-by-step explanation:
We have got the lines :

Both lines intercept the x-axis in the point :

In all point from x-axis the y-component is equal to 0.

We replace the I point in the lines equations:

From the first equation :

From the second equation :

Then 
Finally :

y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc
Answer:
25
Step-by-step explanation:
since the angle in question is across from angle 70, they are congruent. You set up the equation
70=20+2p
50=2p
25=p
The product of 8 times 80 is 640. An easy way to find this is to multiply 8 by 8, then multiply the product by 10.
I hope this helped! :)
