Answer:
Step-by-step explanation:
<u>We know that:</u>
- sin 30° = 1/2, therefore arcsin (1/2) = 30°
- tan 45° = 1, therefore arctan (1) = 45°
<u>So the value of the expression is:</u>
- arcsin (1/2) + arctan (1) = 30° + 45° = 75°
Answer:
The answer is 57.83
Step-by-step explanation:
find 8% of 45.90 and add 18% of 45.90 and add them together.
8%*45.90=3.67
18%*45.90=8.26
Add, 45.90+8.26+3.67
The final price of your meal is 57.83
