Answer:
A. Hypotenuse-leg (HL) congruence.
HL, when you have 2 right triangles and their hypotenuses are congruent you are able to say HL
Step-by-step explanation:
We know that the hypotenuse-leg theorem states that if the hypotenuse and one leg of a right triangle are congruent to hypotenuse and corresponding leg of another right triangle, then the triangles are congruent.
hypotenuse(AB) of △BDA equals to hypotenuse (CD) of △DBC.
BDA and DBC share a common side DB.
Using Pythagorean theorem we will get,
We have been given that CD=AB, Upon using this information we will get,
Upon subtracting from both sides of our equation we will get,
Answer:
see the explanation
Step-by-step explanation:
we know that
A gross is equal to 120 ones or ten dozen
what is 15 tens - 1 gross
we know that
15 tens means ----> That you are adding 10, 15 times or multiplying 10 by 15, which gives you
1 gross means ---> That you are adding 10, 12 times or multiplying 10 by 12
which gives you
so
The algebraic expression of 15 tens - 1 gross is equal to
Convert to word expression
3 tens
<h2>Answer:</h2>
The graph is shown in the Figure below
<h2>Step-by-step explanation:</h2>In this exercise, we have an equation. On the left side we have a straight line with slope and there is no any y-intercept. On the right side, on the other had, we also have a straight line, but the slope here is
. Therefore, by plotting these two straight lines, we have that the solution is the origin, that is, the point
.
