Answer:
15
Step-by-step explanation:
Pythagorean theorem states that the hypogenous of a right triangle is 
. The hypogenous is the longest part of the triangle which is directly across from the 90 degree angle.
a = 9
b = 12
so,
Answer:
6
Step-by-step explanation:
One fourth is ÷4
24÷4=6
I believe it is 973 miles if you just add the amount on Tuesday + the amount on Wednesday so....
475+498=973
Answer:
Step-by-step explanation:
<ACB = <ECD
These 2 angles are vertically opposite and are equal.
<B = <D
They are both right angles are therefore equal.
The answer is the AA postulate.
A
Note
ASA is a congruence postualate. If S is between two angles that can be shown to be corresponding and equal, then you will have 2 congruent triangles.
SSS if three sides of 1 triangle = 3 sides of a second triangle, then the 2 triangles are congruent. If the the three sides of one triangle are in a ratio with 3 sides of the other triangle, then the triangles could be similar, but that is not the case here.
SAS this is the terminology for congruence as well. We don't know enough to use it for similarity. Some sort of ratio would have to be mentioned to do that.
You are intended to use AA as your answer.
