Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.


The 3 inside angles of a triangle must equal 180 degrees.


The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.


Since the 2 bottom angles would be the same, divide 142 by 2 to get x.

X = 142 / 2 = 71 degrees.

An horse gallops 200ft turns and trots 350ft turns again and travels 410ft
bija089 [108]

The area of the triangle formed by his path is 34971.98 ft sq to the nearest hundredth.

<h3>What is the Heron's formula?</h3>

The Heron's formula is given as;

√s(s-a)(s-b)(s-c)

where s is half the perimeter of the triangle

WE have been given that horse gallops 200ft, turns and trots 350ft, turns again and travels 410ft to return to the point he started from.

Perimeter of the triangle is given as = 200 + 350 + 410 = 960 ft

Semi perimeter =  960 ft/ 2 = 480 ft

Area =  √s(s-a)(s-b)(s-c)

Area =  √480 (480 -200)(480 -350)(480 -410)

Area =  √480 (280)(130)(70)

Area =  √480 (2548000)

Area = 34971.98

The area of the triangle formed by his path is 34971.98 ft sq to the nearest hundredth.

Answer:

Hello Adam here!

Step-by-step explanation:

The numbers that are represented by decimal numerals are the decimal fractions (sometimes called decimal numbers), that is, the rational numbers that may be expressed as a fraction whose denominator is a power of ten.

What makes 50.652 rational?
Ivanshal [37]
Remember a rational number is a number that can be written with two whole numbers in a fraction, for example, 0.25 can be written as 1/4 notice how, both, the numerator and denominator are whole numbers AKA Integers(numbers that aren't decimals or fractions).

any number that can't be written by whole numbers in the numerator or denominator is an irrational number, things like Pi, Pi cannot be written by two whole numbers in the fraction. 

50.652, is definitely rational because the fraction does not need decimal numbers in the numerator or denominator.

it can be written as:
50 \frac{50}{50} or \frac{12663}{250}

notice how neither the numerator or denominators are decimals?
