Find the measure of side c. Triangle A B C has a right angle at angle C. The measure of angle A is 29 degrees. Hypotenuse A B is
Pavel [41]

Given:

In triangle ABC, right angle at angle C.

a = 33 meters

m\angle A=29^\circ

To find:

The measure of side c.

Solution:

In a right angle triangle,

\sin \theta =\dfrac{Perpendicular}{Hypotenuse}

It is also written as:

\sin \theta =\dfrac{Opposite}{Hypotenuse}

In triangle ABC, angle C is a right angle. It means the side c is the hypotenuse.

In triangle ABC,

\sin A=\dfrac{a}{c}

\sin 29^\circ=\dfrac{33}{c}

c=\dfrac{33}{\sin 29^\circ}

On further simplification, we get

c=\dfrac{33}{0.4848}

c=68.0693

c\approx 68.07

Therefore, the measure of side c is 68.07 meters.

scoundrel [369]

Answer:

30 mm

Step-by-step explanation:

The volume of a rectangular prism is the product of its three dimensions. To find the missing dimension, divide the volume by the product of the two that are given:

(165000 mm^3)/((100 mm)(55 mm)) = 165000/5500 mm^3/mm^2 = 30 mm

Hi! Algebra two question, rational exponents.
ivanzaharov [21]

Simplifying \left(x^2+8xy+16y^2\right)^{\frac{1}{3}}.\left(x+4y\right)^{\frac{1}{3}} we get \left(x+4y\right)}

Step-by-step explanation:

We need to simplify:

\left(x^2+8xy+16y^2\right)^{\frac{1}{3}}.\left(x+4y\right)^{\frac{1}{3}}

For solving, we will first simplify the terms inside the exponent and then solve exponent

First Solving: \left(x^2+8xy+16y^2\right)}.\left(x+4y\right)}

Using the formula: (a^2+2ab+b^2)=(a+b)^2

\left(x^2+8xy+16y^2\right)}.\left(x+4y\right)}\\\left((x)^2+2(x)(4y)+(4y)^2\right)}.\left(x+4y\right)}\\\left(x+4y\right)^2}.\left(x+4y\right)}

Using exponent rule:

a^m.a^n=a^{m+n}

\left(x+4y\right)^{2+1}}\\\left(x+4y\right)^3}

Now,

(\left(x+4y\right)^3})^{\frac{1}{3}}\\Simplifiying:\\\left(x+4y\right)}^{\frac{3}{3}}\\\left(x+4y\right)}

So, simplifying \left(x^2+8xy+16y^2\right)^{\frac{1}{3}}.\left(x+4y\right)^{\frac{1}{3}} we get \left(x+4y\right)}
