Triangles are congruent when they have exactly the same three sides and exactly the same three angles.
The diagram shows two pairs of congruent triangle:
- triangle C is congruent to triangle E (have exactly the same three sides and exactly the same three angles);
- triangle D is congruent tot triangle F (have exactly the same three sides and exactly the same three angles).
Triangles A and B apears not to be congruent to any others triangles.
This is classic Pythagorean solving:
Side^2 + Side^2 = Hypotenuse^2
The hypotenuse is the longest side of a triangle, and it connects the leg and the base usually. In this triangle, 18 is the hypotenuse -- so since we are solving for the unknown side, the equation is:
a^2 + 5.7^2 = 18^2 -- now solve
a^2 = 18^2 - 5.7^2
a^2 = 291.51
a = sqrt(291.51)
a = 17.07 -- because height is the square root of the difference of the squares of 18 and 5.7
The answer is choice B.
Answer:
1.6448 * 10^4.
Step-by-step explanation:
16448
There are 4 digits after the first so the exponent is 4.
1.6448 * 10^4.
Answer:
(x^2-6)^2
Step-by-step explanation:
The number 4 represents the initially held water of the bucket. Then the correct option is B.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A bucket holding several inches of water was placed under a leaking faucet.
Water leaking into the bucket so that the level of the water in the bucket increased by a certain number of inches per hour.
The equation y = 2x + 4 represents this situation, where x is the number of hours and y is the number of inches of water in the bucket.
Then the number 4 in the equation represents.
The number 4 represents the initially held water of the bucket.
