Equation
2/3 = 14/ x
Cross multiply
2xX = 14x3
2x = 42
Eliminate
2x/2 = 42/2
X = 21
Answer:
A=35, B=55, and C=25
Step-by-step explanation:
Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.
if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B
Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.
slope intercept form
y = mx +b
x-y =8
subtract x from each side
-y = -x+8
divide by -1
y = x-8
Choice C
If a circle has radius
R, its circumference equals to
2πR where π is an irrational number that, approximately, equals to
3.1415926
