m∠A + m∠B = 90
(3x + 5) + (2x - 15) = 90
(3x + 2x) + (5 - 15) = 90
5x - 10 = 90
+ 10 + 10
5x = 100
5 5
x = 20
m∠A = 3x + 5
m∠A = 3(20) + 5
m∠A = 60 + 5
m∠A = 65
m∠B = 2x - 15
m∠B = 2(20) - 15
m∠B = 40 - 15
m∠B = 25
<h2>
Answer:</h2>
<h2>15x=8</h2>
as according to law if a number is multiplied at one side then it will be divide to other side
so
<h2>x=8/15</h2>

ANSWER
The correct answer is A
{
}
<u>EXPLANATION</u>
This implies that
We solve the compound inequality to obtain,
Remember that, dividing through by negative 1 reverses the inequality sign
The solution set is
{}
The answer is C, "ABCD are right angles", because rectangles only have 90 degree angles.
