Question

Find X in the given right angled triangle ABC i) angle B=90 degree

Answer 1

Answer:

x = 3

Step-by-step explanation:

Using the pythagoras theorem;

hyp^2 = opp^2 + adj^2

(x+2)^2 = 5^2 + (x-3)^2

Expand

x²+4x+4 = 25 + x²-6x+9

x²+4x+4-25-x²+6x - 9 = 0

10x - 30 = 0

10x = 30

x = 30/10

x = 3

Hence the value of x is 3
