Question

Find m 10 years ago

Answer 1

"bisects" means splitting into two equal halves

Answer 2

therefore the measures \(4x-25\) and \(2x+5\) are equal :
\[4x-25 = 2x+5\]

solve \(x\)

Answer 3

Would I add the 4x and 2x and then the -25 and 5?

Answer 4

The goal here is to isolate \(x\),
you start by adding 25 both sides so that that left hand side becoems simpler :
\[4x-25+25 = 2x+5+25\]
\[4x = 2x+30\]

Answer 5

Would I then subtract 2x from 4x?

Answer 6

Yes!

Answer 7

thank you! I'm not too smart lol

Answer 8

You're smart enough

Answer 9

\[4x = 2x+30\]

subtract 2x both sides and get
\[2x= 30\]

divide 2 both sides
\[x = 15\]

Answer 10

plug that in the earlier expression for angle
