Question

What is m 11 years ago

Answer 1

How do you figure this out?

Answer 2

do u want me to explain or want a direct ans?

Answer 3

Explain, Please.

Answer 4

ok

Answer 5

now sum of all three angles of a triangle is?

Answer 6

180.

Answer 7

yup now first find out m<BAC
m<BAC + 85 + 25 = 180
m<BAC = 180 - 85 - 25
m<BAC = ?

Answer 8

u'll get m<BAC=70

Answer 9

no angle of a straight line is 180
so
m<BAC + m<BAD = 180
70 + m<BAD =180
m<BAD = 180 - 70
m<BAD = 110

Answer 10

Explain for this one, so I can get the hang of it. Please.

Answer 11

which one? @allibricker12

Answer 12

now m<BAD + m<BAC = 180
130 + m<BAC = 180
m<BAC = 180 - 130
m<BAC = 50
so
50 + 20 + m< ABC = 180
m<ABC = 180 - 50 - 20
m<ABC = 110

Answer 13

So it's 110 again. Or?

Answer 14

You could also use the remote interior angle theorem. But it's very similar to what is already explained.

Answer 15

yes 110 again

Answer 16

can you help me out with 2 more. They are alittle different from these.

Answer 17

@jim_thompson5910
remote interior angle theorem = exterior angle theorem ;D

Answer 18

Which is an exterior angle of triangle ABC?

Answer 19

remote interior = exterior
