Wouldn't the answer be: 435.84m
Answer:
42.42 yards
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A right triangle has a leg of length 15 yards and a hypotenuse of length 45 yards .
And we need to find the length of other leg. So since it is a right angled triangle we can use the Pythagoras Theorem which is ,
<u>Pythagoras</u><u> Theorem</u><u> </u><u>:</u><u>-</u><u> </u>
- In right angle triangle sum of squares of two smallest sides that is base and perpendicular is equal to the square of the largest side that is hypotenuse .
<u>Using</u><u> Pythagoras</u><u> Theorem</u><u> </u><u>:</u><u>-</u><u> </u>
p² + b² = h²
15² + p² = 45²
225 + p² = 2025
p²= 1800
p = 42.42
<u>Hence </u><u>the</u><u> </u><u>measure</u><u> of</u><u> </u><u>other </u><u>leg </u><u>is </u><u>4</u><u>2</u><u>.</u><u>4</u><u>2</u><u> </u><u>yards.</u>
X=0
Y=5
That’s the answer because you cancel out the x by taking away so ur left with 10-2y+3y=15
Y=15-10
Y=5
So put 5 in the equation and x=0
Rearrange the equation by writing
x² + x - 90 = 0
x² + x = 90
x² + x + 1/4 = 90 + 1/4
Recall that (a + b)² = a² + 2ab + b². Then
x² + 2 • x/2 + (1/2)² = 361/4
(x + 1/2)² = 361/4
x + 1/2 = ± √(361/4)
x = -1/2 ± 19/2
x = 9 or x = -10
