Question

Two angles of a triangle measure 35° and 45°respectively. Find the measure of the third angle. Also state what type of triangle is this?

Answer 1

Answer:

Step-by-step explanation:

Angle A= 35degrees

Angle B = 45 degrees

Angle  C =?

Angle A+ Angle B + Angle C= 180 degrees

35degrees+45degrees+Angle C=180degrees

80 degrees +Angle C = 180 degrees

Angle C = 180degrees- 80 degrees

= Angle C= 100 degrees

This is scalene triangle

Answer 2

Answer:

total angle of a triangle =180°

angle1 = 35°

angle2 = 45°

angle3 = 180-(35+45)

= 180-80

= 100°

as one angle is greater than 90

so it is a obtuse angle triangle
