Mathematics
1 answer:
aliya0001 [1]3 years ago
4 0

Answer:

step 1: x+50+4x=90

the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.

step 2: x+50+4x=90

                  x+4x=50

                      5x=50

                        x=10

then you solve the equation, x is 10
