I need to find the angles of A and B. From what I know, they should be congruent, but I've been stuck for wayyyy to long.​
ANTONII [103]

Answer:

Step-by-step explanation:

If I'm not mistaken, the 76 degrees means that a is equal to 76 deg. Just visually, if you were to widen that angle, similarly, a would grow just as much.

If you know that a = 76d, b = 76d as well

Answer: \sqrt{3} x 8 = 13.8564064606

Step-by-step explanation: The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3 (\sqrt{3}). Therefore, square root 3 (\sqrt{3}) is multiplied by the length (8 in our case) of either 6 faces of the cube.

amid [387]

Answer:

Step-by-step explanation:

-60

Decrease in population is represented by negative sign

Change in population in 1 year = -300\5

                                                = -60
