Answer 1

○=> Correct option :

$\color{plum}\tt\bold{(C) \: 120}$

Steps to derive correct option :

Given :

Measure of an angle = 15°

Measure of the second angle = 45°

Let the measure of the third angle be x.

We know that :

▪︎Sum of all angles of a triangle = 180°[angle sum property]

Which means :

$=\tt 15 + 45 + x = 180$

$=\tt 60 + x = 180$

$=\tt x = 180 - 60$

$\hookrightarrow\color{plum}\tt \: x = 120°$

Thus, the measure of the third angle = 120°

Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.

Therefore, the correct option is (C) 120

Answer 2

Answer:

120

Step-by-step explanation:

all angles of a triangle add up to 180. 180-15-45= 120.
