Question

Q.No.4. Two angles of triangle are 45° and 55º. Find the measure of third angle​

Answer 1

Answer:

80 degrees

Step-by-step explanation:

let the missing angle be x

we know sum of angles of a triangle is 180°

so, the equation formed

45 + 55 + x = 180

100 + x = 180

x = 180-100

x = 80°

Answer 2

Answer:

• A triangle has a total of 180°

First angle=45°

2nd angle=55°

Sum of 2 angles=100°

therefore, third angle=180°-100°

=80°
