Question

The angles of a triangle are ( x + 10 )° , ( x + 40 )° and ( 2x + 30 )°. Find the measure of all the angles and assign a special name of the triangle.

Answer 1

Answer:

Step-by-step explanation:

as we now sum of all sides of triangle = 180°

so according to the question

x+10°+x+40°+2x+30° = 180°

4x + 80° = 180°

4x= 180°-80°

4x =100°

x = 100/4

x= 25°

so,

x+10° = 25+10 = 35°

x+40° = 25+40 = 65°

2x+30 = 25x2 + 30 = 80°

verification

35+65+80 = 180

Answer 2

Answer:

x=25°

Value of 2x+30={2×25+30}°=80°

Value of x+10°={25+10)°

value of x+40°={25+40)°=65°
