Question

RS bisects angle QRT, measure angle QRS-93x+80 degrees, and measure angle SRT=(9x-4) degrees. find measure angle SRT

Answer 1

oops QRS= (3x+8) degrees

Answer 2

when line bisects an angle it splits it into 2 equal angles
therefore QRS = SRT

3x+8 = 9x-4

Answer 3

so does that mean the SRT is just 9x-4?

Answer 4

well yes but you can solve for x

Answer 5

or i still need to solve both sides?

Answer 6

oh ok

Answer 7

yes combine terms, get x's on one sides, constants on other

Answer 8

ok thank you :)

Answer 9

then plug the x value into 9x-4 to get a number for SRT :)

Answer 10

ok :)

Answer 11

let me know what you get, i'll check your answer for you if you like

Answer 12

i got x=2 then 9(2)-4=14
so angle SRT = 14?

Answer 13

perfect
good job

Answer 14

wow thank you so much :) you made it way easier for me to understand!

Answer 15

no problem
so what do you think angle QRT is?

Answer 16

would it be double what SRT is because SRT is half of QRT? so like 28

Answer 17

yes
good thats exactly the right kind of thinking
since it bisects it into 2 equal angles, if you double the angle you get the starting angle

Answer 18

sweet :) man i wish my math teacher was like you, hes doesnt teach us anything he just gives us the homework assignment and we copy the notes off the board

Answer 19

cool that's good to hear, i'm planning on being a math teacher

Answer 20

thats good, i think you make a super good math teacher!

Answer 21
