Answer:
concave pentagon
Step-by-step explanation:
Just do 3x+5+2x=90 And solve for x.
So, 5x+5=90
5x=85
x=85/5 = 17
now you know the value of x, so you can calculate the angles.
Btw the total angle of a triangle is 180, and since this is a right angle triangle, you know that the two angles added together needs to equal 90.

Answer:
don't know? SORRY!!!!!
Step-by-step explanation:
The slope of any line on the x-y plane is expressed as the rise divided by the run - the "rise" here is the change in the y coordinate, and the "run" is the change in the x coordinate. Given -4 and 8 as your y coordinates in this problem, and 3 and -1 as your x coordinates, how can you find the change - or difference - in each? Once you have those, you'll just need to put the
