It's an isosceles triangle, therefore m∠B = m∠C.
We have the equation:
2x + 10 = 3x - 5 <em>subtract 10 from both sides</em>
2x = 3x - 15 <em>subtract 3x from both sides</em>
-x = -15 <em>change the signs</em>
x = 15
m∠B = (2x + 10)°
m∠B = (2 · 15 + 10)° = (30 + 10)° = 40°
We know, the sum of measures of a tringle is equal 180°.
m∠A + m∠B + m∠C = 180°
m∠B = m∠C = 40°
<h3>Answer: ∠B = 40° and ∠C = 40°</h3>

The correct answer is C.
Perpendicular lines have opposite reciprocal slopes. This mean you will flip the original number upside down, and change its sign (negative to positive and vice versa). So, the opposite of -1/4 will be 4.
The school can charge $7.54 for each agenda book.
Step-by-step explanation:
Given,
Purchase price of 350 books = $1137.50
Profit they want to make = $1500
Total amount = 1137.50 + 1500 = $2637.50
Therefore;
The school must sell 350 books for $2637.50
Thus,
350 books = 2637.50 dollars
1 book = 
1 book = $7.535
Rounding off to nearest cent
1 book = $7.54
The school can charge $7.54 for each agenda book.
