Answer:

We need to start with 5 kg of mushrooms

Step-by-step explanation:

The total of the dried mushrooms = mushrooms *  percentage of weight kept

percentage of weight kept = 1- 80% = 20 %

We want 1 kg of dried mushrooms.   Substitute in what we know

1 kg = mushrooms * 20%

1 kg  = mushrooms * .2

Divide  each side by .2

1 /.2 = mushroom *.2 /.2

5 kg = mushrooms

We need to start with 5 kg of mushrooms

I need help solving this problem with proofs if at all possible
k0ka [10]

I don't really like these algebra problems which pretend to be geometry.

The bisector makes two equal angles, so

x/2 + 17 = x - 33

50 = (1/2) x

x = 100

That means ABC = 100/2 + 17 = 67 degrees

CBD = 100 - 33 = 67 degrees, equal so that checks

We're asked for ABC which is 67 + 67 = 134 degrees

Answer: 134°
