Question

In ∆ABC, ㄥA = x°, ㄥB = y°. If 3x - 5y = 30◦ and the triangle is a right angled triangle, find x and y.

Answer 1

Answer:

sum of angle in triangle =180degrees

x+y+90degrees=180degrees

x+y=90degrees

3x-5y=30degrees

5x+5y=450degrees

8x=480degrees

x=60degrees

60degrees+y=90degrees

y=30degrees
