Question

how do you solve this?
Find the measure of angle ABC.
A.124
B.97
c.56
d.51

Answer 1

sum of angles in a tri-angle is 180........form ann en nd solve it

Answer 2

u shud get 56

Answer 3

Angles in a triangle all add up to 180˚ so...

\[32+2x-15+x-5=180\]
\[3x+12=180\]
\[3x=168\]
\[x=56\]

Substitute x=56 into angle ABC (x-5)˚

Angle ABC = 56-5 = 51˚

So the answer is D :)

Answer 4

SO IS IT 56 OR 51?

Answer 5

It's 51

Answer 6

Because you have to substitute x=56 into (x-5)˚ for angle ABC

Answer 7

OKAY THANK YOU

Answer 8
