Answer:
1 1/2 cups
Step-by-step explanation:
2/3 cup of almonds = 4 cups of trail mix
4 cups of trail mix = 2/3 cup of almond
4 cups of trail mix = 2/3 cup of almond
1 cup of trail mix = 2/3 ÷ 4 = 1/6 cup of almond
1 cup of trail mix = 1/6 cup of almond
9 cups of trail mix = 1/6 x 9 = 3/2 cup of almond
3/2 cups = 1 1/2 cups
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
ANSWER:
For the first picture, it is the first answer. This is because of the Exterior Angle Theorem.
For the second picture, use the Exterior Angle Theorem again, but this time, solve for x.

The m∡B = 39°
