Answer:

I only know the answer to part A. The triangles ARE similar and they ARE congruent.

Step-by-step explanation:

The big triangle has 75° and 60°.

The little triangle has 75° and 45°

75°+60°+45° = 180°

45° is the missing interior angle for the big triangle.

75°+45°+60° = 180°

60° is the missing interior angle for the little triangle.

Josh had to make 2,000 cookies for his bakery. 2 pieces of wheat make 8 cookies. How much wheat does he need?
Licemer1 [7]
Answer: 500 pieces of wheat

Explanation:

First: set up the proportion
Cookies:wheat = 8:2
Simplify = 4:1
We need to find how much wheat he needs for 2,000 cookies.
We need to assign a variable for wheat
Wheat = W
If Josh needs to make 2,000 cookies he would need W amount of wheat
Original proportion = 4:1
For 2,000 cookies = 2,000:W
To get from 4 to 2,000
2,000/4 = 500
So W/1 = 500
Isolate the variable:
w/1 (1) = 500/1
W = 500
