at Alan's sports shop, GO FAST trainers cost £40.95 originally and there is a third off in the sale. At Irene's sport shop, GO

dem82 [27]

The trainers will be cheaper at Alan's sport shop.

prices ->
Alan's: 27.30
Irene's: 28.00

$\frac{1}{3}$ of 40.95 can be calculated as follows ->

$\frac{1}{3}$ = $\frac{x}{40.95}$
simplify to get that x = 27.30

30% of 40.00 can be calculated as follows ->

$\frac{30}{100}$ = $\frac{x}{40.00}$
simplify to get that x = 28

The triangle shown is a right triangle. Create the equation to be used to find the missing lengths.

telo118 [61]

The equation used to find the missing lengths:
9 = __SR (5^2 + x^2)__
As long as it is a right triangle, this is called the Pythagorean Theorem
${9}^{2} = {x}^{2} + {5}^{2} \\ \sqrt{ {9}^{2} } = \sqrt{( {x}^{2} + {5}^{2} )} \\ 9= \sqrt{( {x}^{2} + {5}^{2} )}$

** FYI- if you wanted to SOLVE FOR THE MISSING SIDE X, then just switch around the original equation solving in terms of x:
${9}^{2} = {x}^{2} + {5}^{2} \\ {x}^{2} = {9}^{2} - {5}^{2} \\ x= \sqrt{( {9}^{2} - {5}^{2})} = \sqrt{(81 - 25)} \\$
$x = \sqrt{56} = \sqrt{(8 \times 7)} \\ x= \sqrt{(4 \times 14)} = \sqrt{4}\times \sqrt{14} \\ x = 2 \sqrt{14}$

The angle formed by the intersection of tangent and secant outside the circle equals half the difference of the <span>intercepted arcs.

</span> $\frac{10x+20-80}{2}=2x+15 \\ 10x-60=2(2x+15) \\ 10x-60= 4x+30 \\ 10x-4x=30+60 \\ 6x=90 \\ x=90/6 \\ x=15$ <span>
