What is the length of side a? Round to the nearest tenth of an inch. Enter your answer in the box. ( Answer in Inches )

Jet001 [13]

Given:

Base of a right triangle = 7 in

Height of a right triangle = a

Hypotenuse = 16 in

To find:

The length of side a.

Solution:

Using Pythagoras theorem:

$\text{Base}^2+\text{Height}^2=\text{Hypotenuse}^2$

$7^{2}+a^{2}=16^{2}$

$49+a^{2}=256$

Subtract 49 from both sides.

$49+a^{2}-49=256-49$

$a^{2}=207$

Taking square root on both sides, we get

a = 14.4

The length of side a is 14.4 in.

In the diagram below, assume that all points are given in rectangular coordinates. Determine the polar coordinates for each poin

Korolek [52]

Step-by-step explanation:

We have cartisean points. We are trying to find polar points.

We can find r by applying the pythagorean theorem to the x value and y values.

$r {}^{2} = {x}^{2} + {y}^{2}$

And to find theta, notice how a right triangle is created if we draw the base(the x value) and the height(y value). We also just found our r( hypotenuse) so ignore that. We know the opposite side and the adjacent side originally. so we can use the tangent function.

$\tan(x) = \frac{y}{x}$
