Answer:
<u>The missing side is 12 cm length</u>
Step-by-step explanation:
1. Let's review the information given to us to solve the case correctly:
Length of the longest side= 13 cm
Length of one leg = 5 cm
2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:
2nd leg² = Length of the longest side ² - Length of one leg²
2nd leg² = 13 ² - 5 ²
2nd leg² = 169 -25
2nd leg² = 144
2nd leg = √144
2nd leg = 12 cm
<u>The missing side is 12 cm length</u>
Completing the square is a method used to solve a quadratic equation by changing the shape of the equation so that the left side is a perfect square trinomial.
The following equation makes more sense to solve it complete squares:
x² + 20x = 52
We have then:
x² + 20x + (10) ^ 2 = 52 + 100
(x + 10) ² = 152
Answer:
The most sense to solve by completing the square is for:
B) x² + 20x = 52
Answer:
1 x 60, 2 x 30, 3 x 20, 4 x 15, 5 x 12, 6 x 10, 10 x 6, 12 x 5, 15 x 4, 20 x 3, 30 x 2, 60 x 1 = 60
Step-by-step explanation:
x = 6
Explanation:
use the pythagorean theorem which is <u>a^2 + b^2 = c^2</u>. 8 goes in either the a or b position and 10 is the longest side so it will go in the c position.
