Question

In Triangle ABC AB=×+5,BC=×,AC=25,BC=×angleB=90degrees find the vaule of ×?​

Answer 1

Answer:

x = 15 is the answer of the expression

Answer 2

Answer:

Step-by-step explanation:

We'll do this question by using Pythagoras Theorem.

H²=P²+B², acc. to figure AC²=AB²+BC²

25²=(x+5)²+x²

625= x²+25+10x+x²

625-25= 2x²+10x

600=2x²+10x

2x²+10x-600=0

2x²+40x-30x-600=0

2x(x+20)-30(x+20)=0

(2x-30)(x+20)=0

2x-30=0. OR. x+20=0

x=15 or -20. Ans.
