Answer:
70.5°
Step-by-step explanation:
22² = (20)²+(18)² - 2(20)(18) cos X
484 = 400 + 324 - 720 cos X
-240 = -720 cosx
1/3 = cos X
= X
X = 70.52877937
Answer:
The error is the exponent in the answer should be 11.
Step-by-step explanation:
When you move the decimal place one spot as they do in the final step to move it from a base 10 to a base 1, we have to add a exponent on. Therefore, it should go from 10 to 11.
