Answer:
m<A=40°
m<B=55°
m<C=85°
Step-by-step explanation:
Add up all the angles to equal 180 because all triangles add up to 180.
(2x+5)+(x+15)+x=180
Simplify.
4x+20=180
Solve for x.
x=40.
Plug x into the equations. Hope this helps.

Answer: 1/13
Step-by-step explanation:
There are 4 twos in a pack of 52 cards. So the probability is 4/52 = 1/13
There are 4 threes in a pack of 52 cards. So the probability is again 4/52 = 1/13
So the probability that a 2 or 3 will be drawn is
1/13 + 1/13 = 2/26 = 1/13
