Answer:
- x = 12
- 3x+1 = 37°
- 10x-11 = 109°
- 3x-2 = 34°
Step-by-step explanation:
Perhaps you want to know the value of x or the measures of the angles?
__
Simplifying the given equation, you get ...
(16x -12)° = 180°
16x = 192 . . . . . . . divide by °, add 12
x = 12
(3x+1)° = (3·12+1)° = 37°
(10x-11)° = (10·12-11)° = 109°
(3x-2)° = (3·12-2)° = 34°
x is 12, and the angle measures are 37°, 109°, 34°.
70 divided by half equals 35 (70/2= 35)
35+20= 55
Hope this helps!
Surface area = 4* pi * radius squared
radius is half the diameter
4 *3.14 * 2^2 = 50.27
Answer:
Step-by-step explanation:
If a and (b - c^9/a) are both positive or both negatives, the quadratic will be either, always positive or negative.they are not both then, quadratic will be be positive for some values and negative for others.
