Answer:
x = 65
Step-by-step explanation:
The angle labeled with the expression " ( 2x + 15 ) " and the angle with the measure of 145° are vertical angles
Vertical angles are congruent (In other words, they are equal to each other)
Hence, 2x + 15 = 145
^ ( Note that we just created an equation that we can use
to solve for x )
Using that same equation we then solve for x
2x + 15 = 145
step 1 subtract 15 from each side
15 - 15 cancels out
145 - 15 = 130
we now have 130 = 2x
step 2 divide each side by 2
130 / 2 = 65
2x / 2 = x
we're left with x = 65
Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,
Theres an infinite amount of numbers because you could have 0.10123 to 0.19998298 its never ending
7x2.2 is 14.4 then you will need to multiply 3x2.2 then add them up
