The 2 triangles are congruent therefore
9x-1 = 10x-10
x= 9
so 80* 2 = 160
angle cad measures 160 degrees
You probably made a typing error in writing s = -3 and wrote s - = 3 instead.
The given expression is:

Substituting the given value of s in the previous equation, we get:

Thus the value of given expression becomes -46 for s = -3
Answer:
B) rotation 180 degrees about the origin
Step-by-step explanation:
Also, what do the words underneath D) say? I think the answer could also be a reflection across y = x.
Answer: Volume: 56
