Question

Find the value of ABC

Answer 1

Are you sure the question is not: Find the value of x?

Answer 2

@ranga yea! it says find the value of <ABC

Answer 3

Okay, I presume by that they mean they want to know all three angles of the triangle.

First find x. Use the fact that the sum of all three angles of a triangle= 180.
Write the equation and solve for x.

Answer 4

@ranga I got x = -2?

Answer 5

The sum of the three angles is: (4x + 7) + (11x - 9) + 32 = 180
Simplify the left and solve for x.

Answer 6

@ranga x = 10?

Answer 7

Yes. Put x = 10 and find the two angles.

Answer 8

@ranga okay i got 47 and 101

Answer 9

Yes.

Answer 10

@ranga but the choices for the answer is
A. 10
B. 47
C.40
D.101
so I'm confused which one it is?

Answer 11

Oh, they are asking for angle ABC. That is the 11x - 9. 110 - 9 = 101.
They are just interested in that one angle.

Answer 12

@ranga so the value is 101 right?

Answer 13

yes.

Answer 14

@ranga thank you! :)

Answer 15

you are welcome.
