Question

Find the missing angle of the triangle:
(a) /_ A = 60°, /_ B = 45°, /_C = ?​
(b) /_ B = 60°, /_ A = 60°, /_C = ?
Explain please if you know​

Answer 1

Answer:

(a) /_C=75

(b) /_C=60

by Angle Sum Property

/_A+/_B+/_C=180 degree

Answer 2

Answer:

(a)<c=75°

(b)<c=60°

Step-by-step explanation:

for (a)

<A=60°

<B=45°

<C=?

all sum of all the angles of triangle are 180°

<A+<B+<C=180°

60°+45°+<C=180°

105°+<C=180°

180-105=<C

<C=75°

for (b)

<C=60°
