Find x in this right triangle
1 answer:
<u>Since the </u><u>triangle</u><u> is right angled, we may use pythagoras theorem to find the third side.</u>
<u>Pythagoras theorem :-</u>
KI^2 + JI^2 = KJ^2
<u>substituting the known values in the formula,</u>
x^2 + 3^2 = 5^2
x^2 + 9 = 25
x^2 = 25 - 9
x^2 = 16
x = √16
x = 4

volume = 308cm³
Answer:
1)X+4=2x-17+10
X. =2x-7-4
11=X
DF=11+4
=15
2)FH~
11x+71=12x+32
12x-11x =71-32
X=39
FH=(11×39)+71+(12×39)+32
=1000
3)57+39+8x-12=180
8x+84-84=180-84
8x=96
X=12
4)11x+2=68
11x=66
X=6
5)114+X+37+X=139
2x+151. -151=139-151
X=-6
