Use the distance formula to see if at least two sides are congruent.
Step-by-step explanation:
If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle
Answer:
B
Step-by-step explanation:
Givens
a = 2 sqrt(3)
b = 3 sqrt(2)
c = ?
Formula
a^2 + b^2 = c^2
Solution
- (2sqrt(3))^2 = 2*2 * sqrt(3)*sqrt(3)
- (2sqrt(3))^2 = 4 * 3
- (2sqrt(3))^2 = 12
- (3sqrt(2))^2 = 3 * 3 * sqrt(2)*sqrt(2)
- (3sqrt(2))^2 = 9 * 2
- (3sqrt(2))^2 = 18
(2sqrt(3)^2 + 3sqrt(2)^2 ) = c^2
4*3 + 9*2 = c^2
12 + 18 = c^2
c^2 = 30
sqrt(c)^2 = sqrt(30)
c = sqrt(30)
Answer
B
Answer:
Kohl = $42
Target = $51.30
Best deal is at Kohl's
Step-by-step explanation:
Given ;
At Kohl's:
Selling price = $60
Friend's and family discount = 30% off
(100 - 30)% * $60
0.7 * 60 = $42
At target :
Purchase price = $38
Markup = 35%
Selling price = (100 + 35)% * $38 = 1.35 * 38 = $51.3
Mrs. Clason will get the best deal at Kohl's.
