A)
a•b=20
a=b
a=b=square root from 20

c•d=30
c=d
c=d=square root from 30

a^2+c^2=d^2
20+30=d^2
50=d^2
d=square root from 50

Area=square root from 50•square root from 50=50

B)
a•b=16
a=b
a=b=square root from 16=4

c•d=36
c=d
c=d=square root from 36=6

a^2+c^2=d^2
4^2+6^2=d^2
16+36=d^2
d=square root from 52

Area=square root from 52•square root from 52=52

love history [14]

Answer:

Set; subset.

Step-by-step explanation:

A group of objects or numbers is called a set while a part of a set is called a subset. The objects or numbers that make up a set are generally referred to as elements or members and are written inside a pair of curly braces {}.

A set can be made up of elements such as numbers, alphabets, people, cars etc.

<em>For instance, Set A = {2, 4, 6, 8, 10, 12} represents all the even number between 1 - 12.</em>

On the other hand, a subset is a part of a larger set.

<em>For instance, comedy movies, horror movies, romance movies, action movies are a subset of movies. </em>

The circle below has a center D and its diameter is 10 feet. Given that m angle A D B equals 35 degree, find the length of major
goldfiish [28.3K]

The length of major arc ACB with angle measure of 325° and diameter of 10 feet is (325/36)π

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

angle of arc ACB = 360° - 35° = 325°

The length of major arc ACB = (325/360) * π * 10 = (325/36)π

The length of major arc ACB with angle measure of 325° and diameter of 10 feet is (325/36)π
