Mathematics

Natalija [7]3 years ago

Answer:

<h2>Y = 108°</h2>

Step-by-step explanation:

Since X and Y are supplementary angles it means that the sum of their angles add up to 180°

To find Y , add X and Y and equate it to 180° and solve

That's

X + Y = 180

Y = 180 - X

X = 72°

Y = 180 - 72

We have the final answer as

<h3>Y = 108°</h3>

Hope this helps you

The side of a triangles are 8cm,12cm,17cm.find its perimeter and its are by using herons formula
Novay_Z [31]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides, that is

perimeter = 8 + 12 + 17 = 37 cm

To use Heron's formula for area (A)

A = \sqrt{s(s-a)(s-b)(s-c)}

where a, b and c are the lengths of sides and s the semi perimeter

s = 37 ÷ 2 = 18.5

let a = 8, b = 12 and c = 17, then

A = \sqrt{18.5(18.5-8)(18.5-12)(18.5-17)}

   = \sqrt{18.5(10.5)(6.5)(1.5)}

   = \sqrt{1893.9375} ≈ 43.52 cm² ( to 2 dec. places )

3 in to 2 ft in simplest form
BigorU [14]
<span>The goal in simplifying numbers is to reduce it that can be best seen in the eye.  Also in converting units, you must take note of the units given in the problem. If you don’t, you would get a lot of errors. Length is the measure of distance and can be best represented by either in SI units or English units.  Example of an SI unit is meter, m, and English unit is feet, ft. You are given 3 inches and 2 feet. You can convert any of the numbers into a number that would feel comfortable to you. I will take 3 inches. Note that there are 12 inches in 1 feet. So divide 3 by 12 and you will get ¼ feet. Then divide 2 feet to ¼ feet and you will get 8.</span>
