1.	In a triangle angle a + angle b =65 , angle b + angle c = 140 dind the value oc angle b and angle c
Answer» Given. Angle A +angle B=65 Angle B + angle C =140To find. Angle B = ?, angle C=? Angle A+angle B +angle C =180 {angle sum property} 65°+angle C=180° Angle C =180°-65° Angle C =115° Again, angle A+angle B +angle C=180° Angle A+140°=180° Angle A =180°-140° AngleA =40°Again, Angle A+ Angle B +Angle C= 180° 40°+angle B+115°=180° Angle B +155°= 180° Angle B=180°-155° Angle B =25°
