Answer:
A. x=√60
Step-by-step explanation:
Divide 4 in half because you are solving half of an isosceles triangle
You formula is x²+2²=8²
Square root what you can: x²+4=64
Isolate the variable: x²=60
Square root both sides, x=√60
Answer:
<h2>L=203 yards</h2><h2>W=52 yards</h2>
Step-by-step explanation:
Step one:
given data
perimeter= 510 yards
let the width be x, width=x
length= (4x-5)-----quadruple mean 4 times
Step two:
the expression for perimeter is
P=2L+2W
510=2(4x-5)+2x
510=8x-10+2x
510+10=8x+2x
520=10x
divide both sides by 10
x=520/10
x=52
the width is 52 yards
the lenght is (4x-5)
L=4(52)-5
L=208-5
L=203 yards
