Answer:
x = 25
Step-by-step explanation:
The two angles form a straight line which is 180 degrees
2x+10 + 4x+20 = 180
Combine like terms
6x+30 = 180
Subtract 30 from each side
6x+30-30 = 180-30
6x = 150
Divide by 6
6x/6 = 150/6
x=25
Answer:
-240
Step-by-step explanation:
You want a85.
Work it out step by step:
a85 = 12 + (85 - 1)(-3)
Subtract 1 from 85.
a85 = 12 + 84(-3)
Multiply the numbers in the brackets.
a85 = 12 + -252
Add 12.
a85 = -240
The surface area of a sphere is π x 4 x radius²
so let the radius be r
π x 4 x r² = 2122.64
r = 13 inches
