Answer:

<em> The value of ∠A = 67.98°</em>

Step-by-step explanation:

The right angled triangle is given as

Given ,

Value of AC = 3 units

Value of AB = 8 units

Value of ∠A = ?

By using Pythagoras theorem,

$AB^{2}$ = $AC^{2} +BC^{2}$

$8^{2} = 3^{2} + BC^{2}$

BC = $\sqrt{55}$

By using Cos A = AC/AB

A = $\cos^{-1}3/8$

A = 67.98°

<em> The value of ∠A = 67.98°</em>

In a rectangular coordinate plane what is the distance between points (-3,0) and (3,8)

zheka24 [161]

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\\\\ \mathsf{d=\sqrt{(3-(-3))^2+(8-0)^2}}\\\\ \mathsf{d=\sqrt{(3+3)^2+(8)^2}}\\\\ \mathsf{d=\sqrt{(6)^2+64}}\\\\ \mathsf{d=\sqrt{36+64}}\\\\ \mathsf{d=\sqrt{100}}\\\\ \underline{\mathsf{d=10}}$

The answer is 10 uc.

Why would engineers and architects need to find angles in a polygon

agasfer [191]

As a engineer who was mechanical then electrical most buildings, schematics,etc require some form of calculation for some shapes seeing that those shapes are what make up the world. Say for example you need to make something like a mother board pro house knowing it's shape and angle helps make a more accurate structure during the blue printing and build phase. No one just goes in and wings it you need to determine angles for things you don't know that the point of it.
