Question

4. Find out which of these form a triangle
(a)ZA = 30°, ZB = 60°, ZC = 90°
(b)ZA = 100°, ZB = 70°, ZC = 30°​

Answer 1

Answer:

(a)

Step-by-step explanation:

sum of angle of triangle should be 180 degree

(a) sum of 30,60,90=180

but

(b) sum of 100,70,30=200

Answer 2

Answer:

a) ZA = 30 °, ZB= 60 ° , ZC = 90 °

= 30 + 60 + 30 = 180 °

b) ZA = 100° , ZB = 70 ° , ZC = 30 °

= 100+70 + 30 = 200 °
