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:
5x+3
Step-by-step explanation:
substitute x for the unknown number
Answer:
P= A + B + C
Step-by-step explanation:
P= Side + base + Side
P= 10 + 6 + 8
P = 24
(-3x + 15) + (-3x + 2)
Simplify by combining like terms.
-6x + 17
-6x + 17
Answer:
Step-by-step explanation:
Given:
ΔCAD and ΔCBD
∠A ≅∠B (Angle)
AD ≅BD (Side)
From the graph we see that
CD≅CD (Side)
because of reflexive propriety ( a line segment is congruent with itself)
If you put in order those congruencies we have SSA witch does NOT prove congruence.
we not use SAS because the angle between the sides is not congruent
