Question

In a Δ , A=x0 , B = (3x)0 and C = yo. If 3y – 5x = 30 , The type of triangle is

Answer 1

Hi, dear

Here is your answer

angle A + Angle B + angle C is equals to 180 degree

X + 3 X + Y is equal to 180 degree

4 x + Y is equals to 180 degree

operating 3 multiply 4 x + Y - 3 Y - 5 x is equal to 3 X 180 - 30 degree

12 x + 5 x is equal to 540 degree minus 30 degree

17 x is equal to 510 degree

x equal to 510 degree divide 17

equal to 30 degree

therefore angle A equal to 30 degree

angle b is equal to 3x is equal to 3×30 degree is equal to 90 degree

Hence, it is a right triangle
