Answer:

The length of the hypotenuse is 26 inches

Step-by-step explanation:

The leg(brace) attached to the wall is 10 inches

Perpendicular = 10 inches

Your surfboard sits on a leg that is 24 inches.

Base = 24 inches

Formula : $Hypotenuse^2 = Perpendicular^2 +Base^2$

$Hypotenuse^2 = 10^2+24^2$

$Hypotenuse = \sqrt{10^2+24^2}$

Hypotenuse = 26

Hence the length of the hypotenuse is 26 inches

In triangle MNO the measure of angle O =90 degrees the measure of angle M =66 degrees and NO = 60 feet Find the length of MN to

serg [7]

Answer:

Length of MN = 65.68 feet (Approx.)

Step-by-step explanation:

Given:

Height of NO = 60 feet

Angle ∠M = 66°

Find:

The length of MN

Computation:

Given triangle is a right angled triangle

So,

NO is a perpendicular

MN is hypotenuse

Using trigonometry functions

Sin θ = Perpendicular / Hypotenuse

Sin 66 = NO / MN

0.9135 = 60 / Length of MN

Length of MN = 60 / 0.9135

Length of MN = 65.68 feet (Approx.)

alex41 [277]

Answer:

There are 240 boys.

Step-by-step explanation:

There are five boys to every three girls in an introductory Chinese course. Given that there are 384 students enrolled in total, we want to determine the amount of students which are boys.

Let b represent the number of boys and g girls.

Since the ratio is 5:3, we can write that:

$\displaystyle \frac{5}{3} = \frac{b}{g}$

And since the total number of students is 384:

$b + g = 384$

From the first equation, cross-multiply:

$5g = 3b$

Solve for g:

$\displaystyle g = \frac{3}{5} b$

Substitute:

$\displaystyle b + \left (\frac{3}{5} b\right) = 384$

Simplify:

$\displaystyle \frac{8}{5} b = 384$

Solve for b:

$\displaystyle b = \frac{5}{8}\left(384\right) = 240$

In conclusion, 240 of the total students are boys.
