Question

HURRY, PLEASE I NEED HELP!!!

the measures of the angle of,triangle, ABC are given by the expressions in the table.

angle measure
A (4x-13)
B 15
C (x+18)

what is the measure of A and C

enter your answers in the boxes


m A=___
m C=___

Answer 1

In a triangle we apply angle sum property of triangle, which is given by:

Sum of angles of triangle =180 degrees.

We are given three angles,

A =(4x-13)

B =15

C =(x+18)

Adding the three angles and equating it to 180,

`(4x-13) +15 + (x+18) =180`

combining like terms

`5x+20 =180`

`5x=180-20`

`5x =160`

x=32

angle A = 4x-13 = 4(32)-13 = 115 degrees.

angle C = x+18 = 32 +18 = 50 degrees.

Answer : angle A is 115 degrees and Angle C is 50 degrees.
