To determine the measure of the angle with the cosine value equal to 0.208, we have to use the inverse trigonometric functions. In this number, we have the arccosine which is also written below.
cos⁻¹(0.208) = 77.9948⁰
Therefore, the measure of the angle with cosine equal to 0.208 rounded to the nearest thousandth is <em>77.995⁰</em>.
Answer:
3 * 10 ^-2
Step-by-step explanation:
When we divide numbers in scientific notation first divide the number portion
2.7 /9 =.3
Then divide the exponents
10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1
.3 * 10 ^-1
We cannot leave the .3 since the first number has to be between 1 and less then 10
Move the decimal 1 place to the right which means subtract 1 from the exponent
3 * 10 ^-2
You can get a parallelogram when the plane cuts opposite faces and is not parallel to any edge.
