Question

In ∆ABC, angleA=angleB + angleC. angleA = 90°. If it further given that angleB = 2angleC, find angleB and angleC.
please tell me fast tomorrow is my test.​​

Answer 1

Answer:

angle a is = angle b + angle c

angle is = 90

so

90 = angle b + angle c

it's given that angle b = 2(anglec)

so

90 = 2(angle c) + angle c

90= 3(angle c)

90/3 = angle c

angle c= 30

as angle b is = 2 of angle c

angle b = 30 * 2 = 60
