Solution 1 :-

Statement : corresponding angles in similar triangles must be congruent .

Answer : True

Solution 2 :-

Statement : The hypotenuse of a right angle triangle has to be opposite of 90 degree .

Answer : True

Reason : We know that the side opposite to largest angle in a triangle is largest . Since in a right angle triangle 90 degree is the largest angle and hypotenuse is the longest side therefore they must be opposite to each other .

To the nearest tenth, find the perimeter of ∆ABC with vertices A(-1,4), B(-2,1) and C(2,1).

swat32

First we need to find the length of each side of the triangle , and for that we need to use the distance formula, that is
$d =\sqrt{(x_{2} -x_{1})^2 +(y_{2} -y_{1})^2}$
$AB = \sqrt{(1-4)^2 +(-2+1)^2}= \sqrt{10}$
$\sqrt{BC} = \sqrt{(1-1)^2 + (2+2)^2}=4$
Perimeter is the sum of all sides.
$Perimeter = AB + BC + AC = \sqrt{10}+4 +\sqrt{18}$
$Perimeter= 11.4$

a company makes 2,500 profit on the sale of 20 products, what is the profit when the company sells 300 products

Morgarella [4.7K]

$37,500 profit

To solve this, find the unit rate by dividing 2500 by 20. This will get you an average of $125 profit made per product sold. Then multiply that by 300 (the number of products sold in total) to get your answer of $37,500 profit total.
