in a right angled triangle if the hypotenuse is 15 cm and the ratio of the other two sides is 3:4 find the measures of the right
wariber [46]

Answer:

the other sides are 9 and 12

Step-by-step explanation:

use the Pythagorean theorem.

a^{2} +b^{2} =c^{2}

you know that c^2 is 225 because 15*15=225

a^{2} +b^{2} =225

(from here on I just plugged numbers in)

3:4=9:12

9^{2} +12^{2} =225

81+144=225

225=225

Yaaaaay!

What are the solution(s) of –x2 + 2x + 3 = x2 – 2x + 3?
Leviafan [203]
-x^2+2x+3=x^2-2x+3  add x^2 to both sides

2x+3=2x^2-2x+3  subtract 2x from both sides

3=2x^2-4x+3  subtract 3 from both sides

2x^2-4x=0  factor

2x(x-2)=0

So x=0 and 2
