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.

If the point (p,-5) is on the graph of the equation 6x-3y=21, find the value of p

miv72 [106K]

$\bf (\stackrel{\stackrel{x}{\downarrow }}{p},\stackrel{\stackrel{y}{\downarrow }}{-5})~\hspace{10em}6x-3y=21\implies 6x-3\stackrel{\stackrel{y}{\downarrow }}{(-5)}=21 \\\\\\ 6x+15=21\implies 6x=6\implies x=\cfrac{6}{6}\implies \stackrel{\stackrel{p}{\uparrow }}{x}=1$

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
