Answer:
a. 86-degrees; angle-2 corresponds to the given angle.
Step-by-step explanation:
Angle 2 is 86 degrees. Whenever a line is bisected by another line, 4 angles are formed. The opposite angles aka the kissing V's have the same angle measurement. Angle 2 and 86-degrees are the kissing V's here, thus they have the same angle measure.
Answer:
87.407
Step-by-step explanation:
circumference = 2*pie*r
= 2*pie*17
=106.8/2
=53.4
53.4+(17*2)
=87.4
Well, lets first start off with combining like terms.
9x + 26 + 7x - 17 = 2x + (-3x) + 5x
9x + 7x + will give you 16x, and 26 - 17 will give you 9. Therefore, the first part of the equation is 16x + 9.
On the other side, you can combine all three terms (2x + 5x - 3x), which will give you 4x.
Using the above steps, you can figure that the answer is 16x +9 = 4x

Answer:
a: 0; b: 1; c: 1; d: ∞; e: 0; f: ∞
Step-by-step explanation:
Simplify the expressions to put the left and right in the same form. Then compare. If the x-coefficients are the same, there will be 0 or ∞ solutions. If they are different, there will be 1 solution.
If the x-coefficients are the same, look at the constants. If they are different, there will be 0 solutions. If they are the same, there will be ∞ solutions.
