Answer: Angles ABD and BAD (B)
Step-by-step explanation: Angles ABD BAD are not congruent angles, since they are the same angles.
Congruent angles are angles that both measure the same in degrees.
In this case, B is your correct answer since that answer has the same angle and not comparing any 2 angles, just the same one.

Answer:
7.5 L of 10% solution and 22.5 L of 30% solution
Step-by-step explanation:
Volume of 10% solution plus volume of 30% solution = total volume of 25% volume.
x + y = 30
Acid in 10% solution plus acid in 30% solution = total acid in 25% solution.
0.10 x + 0.30 y = 30 × 0.25
0.10 x + 0.30 y = 7.5
Solve the system of equations, using either substitution or elimination. I'll use substitution:
x = 30 − y
0.10 (30 − y) + 0.30 y = 7.5
3 − 0.10 y + 0.30 y = 7.5
0.20 y = 4.5
y = 22.5
x = 30 − y
x = 7.5
Sarah needs 7.5 L of 10% solution and 22.5 L of 30% solution.

If f(x) is an odd. one-to-one function with f (5) = -2 then which point must lie on the graph of its ... Solve the equation f(x) = g(x) for all values of x. ... (3) (-4.10). 1. 2.64x+4 +y2-10y+25 =-12+4+25. (x+2)(x+2) +ly-sly-5)= 17.
Answer:
C, or 18.0
Step-by-step explanation:
The SAS theorem provides that the area is 17.97, which rounds up to 18.0, giving you C as the answer. The other two are far too high for the given values.
