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
Answer:
or around 57.88
Step-by-step explanation:
We can find the base length by using the formula for the area of a triangle.

Plug in the values that we know, the area and the height, and solve for
.


or about 57.88 if you round to the nearest hundredth.
Wouldnt you need it to equal something? like a-5=b so then b+5=a
Correct hence this answer
