Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
Answer:
D. Similar, AA similarity, ΔSCD
Step-by-step explanation:
CD and RQ are parallel. Therefore, ∠Q and ∠D are corresponding angles, and ∠R and ∠C are also corresponding angles. Corresponding angles are congruent.
Therefore, by AA similarity, ΔSRQ ~ ΔSCD.
12, because 150/25=6x2 is 12
The first one is $240, and the second one is $235.20
This should be answer 3x^2-7y^2=5. by moving5 to the other side it becomes positive so, 0 becomes 5.
