To find the hypotenuse the formula would be:

c^2 = a^2 + b^2

BUT! These two questions ask for the length of the smaller sides, so we need to rearrange the formula to:

a^2 = c^2 - b^2

Where c is the hypotenuse, and b is the other known length. Use this formula to solve the length of the unknown side. 

Let's call the unknown side x,

1) a^2 = c^2 - b^2
    x^2 = 17^2 - 15^2
    x^2 = 64
    Square root both sides to get x
    x = 8

2) a^2 = c^2 - b^2
    x^2 = 26^2 - 24^2
    x^2 = 100
    Square root both sides to get x
    x = 10

Hope this helped! Ask me if there's any part of the working you don't understand :)

A^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 289 - 225
a^2 = 64
sqrt of 64 = 8
a = 8
x = 8

sdas [7]

Answer: L ≈ 2.0 m

Step-by-step explanation:

Lsin40 = h

Lsin55 = h + 0.35

Lsin55 = Lsin40 + 0.35

Lsin55 - Lsin40 = 0.35

L(sin55 - sin40) = 0.35

L = 0.35 / (sin55 - sin40)

L = 1.98452 ≈ 2.0 m

Pick the expression that matches this description:
Katen [24]

Option C is correct because it is a trinomial with a leading coefficient of 3 and a constant term of -5

Step-by-step explanation:

We need to pick the expression that matches this description:

A trinomial with a leading coefficient of 3 and a constant term of -5

First lets explain the terms:

Trinomial: a polynomial having 3 terms

Leading coefficient: The constant value of variable having highest power

Constant term: Having no variable and value cannot be changed.

Now using these definitions, we can choose the correct option

Option A is incorrect because the expression has 2 terms

Option B is incorrect because it is a trinomial but the leading coefficient is -5 and not 3 constant term is 3 and not -5.

Option C is correct because it is a trinomial with a leading coefficient of 3 and a constant term of -5

Option D is incorrect because it is a trinomial but the leading coefficient is 3 but constant term is 1 and not -5.

So, Option C is correct.

Find a direct relationship between x and y.<br> x = 3t and y = 2t + 7
ikadub [295]

Answer:

y = \frac{2}{3} x + 7

Step-by-step explanation:

Given

x = 3t ( divide both sides by 3 )

\frac{1}{3} x = t

Substitute this value into y = 2t + 7

y = 2 × \frac{1}{3} x + 7 = \frac{2}{3} x + 7
