Question

find the value of x.​

Answer 1

Answer:

x = 105

Step-by-step explanation:

sum of all angles of a triangle = 180

= 45 + 30 + x = 180

= 75 + x = 180

x = 180 - 75

x = 105

hence x = 105

hope it helps u plz mark me brainliest

Answer 2

Answer:

the value of x=180°-(45°+30°)

because the sum of three angle of a triangle=180°

x=180°-75°

x=105°

So, the third angle=105°
