**ML Aggarwal CBSE Solutions Class 7 Math 10th Chapter Triangle and its Properties Exercise 10.2**

Sum of angles in triangle = 180

x + y + z = 180

=> 48 + 37 + z = 180

=> 85 + z = 180

=> z = 180 degree – 85 degree

=> z = 95 95 degree

**(8) One of the angles of a triangle measures 80 degree and the other angles are equal. Find the measure of each of the angles.**

**(9) If one angle of a triangle is 60 degree and the other two angles are in the ratio 2:3, find these angles.**

**Solution: **

**(10) If the angles of a triangle are in the ratio 1:2:3. find the angles. Classify the triangle in two different ways.**

**(11) Can a triangle have three angles whose measure are**

**(i) 65 degree, 74 degree, 39 degree**

**(ii) 1/3 right angle, 1 right angle, 60 degree?**

**Solution: **

It is wrong

It is wrong
