Question

5. Two angles of an obtuse angled triangle are 105° and 30°. Find the third angle.
6. One of the angles of a triangle is 100° and the other two are equal. Find the measure of
each of them

Answer 1

Answer:

5. 45° ,6. 40°

Step-by-step explanation:

5. sum of all angles of triangle=180°

let the third angle be x

105+30+x=180

135+x =180

x=180-135=45°

6. let the measure of other angles be x

100+x+x=180°

100+2x=180

2x=180-100=80°

x=80/2=40°

other angles measure 40°
