Answer:
x = 30
Step-by-step explanation:
here 50 is hypotenuse as it is opposite of 90 degree.
x and x + 10 are the two other smaller sides of a right angled triangle respectively.
using pythagoras theorem,
a^2 + b^2 = c^2
x^2 + (x + 10)^2 = 50^2
x^2 + x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 - 2500 = 0
2x^2 + 20x - 2400 = 0
2(x^2 + 10x - 1200) = 0
x^2 + 10x - 1200 = 0
x^2 + (40 - 30) - 1200 = 0
x^2 + 40x - 30x - 1200 = 0
x(x + 40) - 30(x + 40x) = 0
(x + 40)(x - 30) = 0
either x + 40 = 0 OR x - 30 = 0
x = 0 - 40
x = -40
x - 30 = 0
x = 30
x = -40,30
since the length and distance is not measured in negative ur answer will be 30

thank u very much . At first i was wrong and giannathecookie i m really sorry
Answer: 76 miles per hour
<u>Step-by-step explanation:</u>
east bound: t = 4, r = x - 18
west bound: t = 4, r = x
d = r * t
680 = 4(x - 18 + x)
680 = 4(2x - 18)
170 = 2x - 18
188 = 2x
94 = x
eastbound: x - 18 = 94 - 18 = 76
Answer:
1668 feet.
Step-by-step explanation:
We know the opposite side of the right triangle and we need the adjacent side, so we use the tangent function.
If the distance required is x (adj side) we have:
tan 41 = opp/adj
tan 41 = 1450/x
x = 1450 / tan 41
= 1668.03
Answer:
I think the third one I'm not sure tho
Answer:
Area is 24
Step-by-step explanation:
The three sides of the triangle are 6, 8, and 10. You could use A² + B² = C² and determine that A² + 36 = 100 to find the missing side is 8.
Then, the area of the square is 6 × 8 = 48. And each triangle that makes up the square is 48 ÷ 2 = 24.
