Answer:

h=\frac{5\sqrt{3} }{3} \,\,m    

Step-by-step explanation:  

Let BC represents 5 feet across the floor, and AB represents the height.

Consider the figure in the attached file.

We know that,

\text{tan}\theta =\frac{\text{Perpendicular}}{\text{Base}}

\implies\text{tan}\,C\ =\frac{\text{AB}}{\text{BC}}

Here, \angle C=30^{\circ},\text{AB}=h\:\text{meters} , \text{and}\:\text{BC}=5\:\text{meters}

So, we have

\text{tan\,30}^{\circ}=\frac{h}{5}

\implies \frac{1}{\sqrt{3}}=\frac{h}{5}\:\:\left [ \because \text{tan\,30}^{\circ}=\frac{1}{\sqrt{3}} \right ]

\implies h=\frac{5}{\sqrt{3} }

\implies h=\frac{5\times \sqrt{3}}{\sqrt{3}\times \sqrt{3} }

\implies h=\frac{5\sqrt{3}}{3 } \,m

Hence, the mat is \frac{5\sqrt{3}}{3 } \,m high of the ground.

Answer:

D. Isosceles triangle

Step-by-step explanation: Triangles have 180 degrees. To figure out this question you have to find the measure of the last angle. 70+55=125. 180-125=55. So the angles are 70, 55, 55. In an isosceles triangle two sides are equal. Because we know that two angles in the triangle are equal we then know that two sides of the triangle are also equal. Hope this helped :)

When Θ = 5 pi over 6, what are the reference angle and the sign values for sine, cosine, and tangent? Θ' = negative pi over 6; s
timama [110]

Answer:

Option C is correct.

Step-by-step explanation:

\theta=\frac{5\pi }{6}

We need to find reference angle and signs of sinФ, cosФ and tanФ

We know that \theta=\frac{5\pi }{6}radians is equal to 150°

and 150° is in 2nd quadrant.

So, Ф is in 2nd quadrant.

And In 2nd quadrant sine is positive, while cos and tan are negative

The reference angle Ф' is found by: π - Ф

=> Ф = 5π/6

so, Reference angle Ф' = π - 5π/6

Ф' = 6π - 5π/6

Ф' = π/6

So, Option C Θ' = pi over 6; sine is positive, cosine and tangent are negative is correct.
