Answer:
- Corresponding Angle Postulate
- Corresponding Angle Postulate
- Reflexive Property
- Similar
Step-by-step explanation:
The pairs of angles referenced in statements 1 and 2 are "corresponding" angles, so the Corresponding Angle Postulate applies.
The Reflexive Property is what says something is the same as itself. This is used in statement 3.
The upshot of the AA Similarity postulate is to say triangles are similar (as in statement 4).
Answer:
r is 32
Step-by-step explanation:
because yes it was y
Answer:
cosθ = 
Step-by-step explanation:
tanθ = -(65/72)
If it is in the 2nd quadrant, this means that y is positive but x is negative
tanθ= opposite/adjacent or (y/x)
tanθ=
We know that the adjacent value = -72 and the opposite value = 65
The hypotenuse can be get by the following
cosθ is just adjacent/hypotenuse
Our adjacent value is -72
Our hypotenuse is 97, therefore
cosθ =
Answer:
0
Step-by-step explanation:(-18)
- + - = +
So
(-18) + (18) is 0
