Answer:
Step-by-step explanation:
3x + 7 + 9x - 43 = 180
12x = 216
x = 18
m∠4 = 3(18) + 7 = 61°
m∠5 = 9(18) − 43 = 119°
Answer: 30
Step-by-step explanation:
72 / 240= .3 x 100=30
The formula for volume of a cylinder is 3.14r^2h.
r = 3
h = 6
3.14 x 3^2 x 6
3.14 x 9 x 6
=169.56

Answer:
x = 155
Step-by-step explanation:
First find the missing angle in the smaller triangle.
We know that the sum of the angles in a triangle is 180 so 35 + 90 + the missing angle = 180 so 180 - (35+90) = 180 - 125 = 55
Since the line above is a straight line, the sum of the angles must equal 180 so 55 + 60 + ? = 180. So 180 - 115 = 65.
The triangle is a right triangle so that means on of the angles is 90. So 65 + 90 = 155, so we have 180 - 155 = 25.
The angle that x is on is also a straight line so that means the angles must add up to 180 so 180 - 25 = 155.
