Answer:
A=61, B=74
Step-by-step explanation:
Because all the angles in a triangle add up to 180:
(2x+4) + (2x-9) + x = 180
If you solve that for x, you will get that x=35. Now you just plug in x to the angles A and B.
Answer:
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle 
= 
225 = 100 + 
so x =
615.44 = (3.14)(radius)^2
<span>radius = square-root of (615.44/3.14) </span>
<span>diameter = radius x 2 </span>
<span>diameter = 28 inches
3.14

200+50+4 I think is the answer
