Using exact values, find the value of:
a. 12 sin 30 degrees ¨C 6 tan 45degrees + sec 45degrees / 52
12-1/2-6*(1) + ¡Ì2/52=¡Ì2/52
12-1/2-6+¡Ì2/52
what should i do next??
b. Sin2A + tan3A/2 - cos A + sec(a+ 15)
Sin2A + tan3A/2 - cos A + sec(a+ 15)= ¡Ì3/2 + 1 - ¡Ì3/2 + ¡Ì2 = 1+¡Ì2
same thing here too.
can u please so me the work.
hopefully this will post more clearly!
12sin 30 degree - 6 tan 45 degree + sec 45 degrees/ 52 =
12¡¤1/2 -6¡¤ 1 + ¡Ì2/52 = ¡Ì2/52
Sin2A + tan3A/2 - cos A + sec(a+ 15)= ¡Ì3/2 + 1 - ¡Ì3/2 + ¡Ì2 = 1+¡Ì2
a. What gets divided by 52?
What does ¨C mean?
What does ¡Ì2 mean?
What does ¡¤ mean?
Begin by realizing that sin 30 = 1/2 and tan 45 = 1
b. You cannot evaluate this unless you know what a and A are.

To find the value of the expression, we need to simplify it step by step.
Given expression: 12 sin(30°) - 6 tan(45°) + sec(45°) / 52
Step 1: Calculate the values of sin(30°), tan(45°), and sec(45°).
sin(30°) = 1/2 (exact value)
tan(45°) = 1 (exact value)
sec(45°) = √2 (exact value)
Step 2: Substitute the calculated values into the expression.
12 * (1/2) - 6 * 1 + √2 / 52
Step 3: Simplify the expression.
6 - 6 + √2 / 52
Step 4: Combine like terms.
(√2 - 6) / 52
So, the value of the expression, using exact values, is (√2 - 6) / 52.

Similar to the previous question, we need to simplify the given expression step by step.
Given expression: sin(2A) + tan(3A/2) - cos(A) + sec(A + 15)
Step 1: Calculate the values of sin(2A), tan(3A/2), cos(A), and sec(A + 15).
Step 2: Substitute the calculated values into the expression.
Step 3: Simplify the expression.
Step 4: Combine like terms.
In this case, you have not provided the values of A, so the specific numerical answer cannot be determined. However, you can follow the same steps as mentioned above to calculate the value of the expression once you have the specific values of A.
