Question

answer the following question with steps

Answer 1

Answer:

(a) 90 + 70 + x = 180

160 + x = 180

x = 180 - 160

x = 20°

(c) the given triangle is equilateral , so all the angles are of 60°

(d) 90 + 65 + x = 180

155 + x = 180

x = 180 - 155

x = 25°

(e) let the other two angles are 'x'

110 + x + x = 180

110 + 2x = 180

2x = 180 - 110

2x = 70

x = 70/2

x = 35°

the other two angles are of 35°
