The length of a hypotenuse of a 30 - 60 - 90 triangle is 11. what is the perimester

Since we know that the hypotenuse is 11 and this is a 30 - 60 - 90 right triangle we can use 11 to find the other sides.

The hypotenuse is 2s, s is the 30 side length.

So s = 11 / 2 = 5.5

The 60 side is s * square root of 3.

5.5 * square root of 3 = about 9.5.

Now that we know all three sides we can add them together to get the perimeter.

11 + 5.5 + 9.5 = 26

:)))

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
