Answer 8

For the last one, the answer is altitude. The altitude is a line that touches the hypotenuse and the 90 degree angle

Answer 9

EG bisects angle DEF means that EG divides angle DEF into 2 equal parts
so we have angle DEG=angleGEF

Answer 10

Let me see tho...

Answer 11

can u find the angle DEG with this information?

Answer 12

Yeah it doesnʻt bisect anything

Answer 13

oh okay

Answer 14

:/ i didn't read that u tagged me for 2nd one

Answer 15

okay

Answer 16

qwerty we are finally here

Answer 17

sum of all angles=180
so 58+62+(2n+10+4n-34)=180

see that 2n+10+4n-34=angleXYZ

so 120+angleXYZ=180
angleXYZ=60
