Answer:
40.5
Step-by-step explanation:
x= ½(122-41)=½(81)= 40.5°
Answer:
-The measure of :
-The measure of (if needed):
Step-by-step explanation:
-Set the measure of on one side and set the measure of on the other side and it will be written as:
-Then, solve for :
-After you have found the value of , plug in both the measure of and in order to get the actual angle measurement of and :
Finding the measure of :
Finding the measure of :
-Notice: That reason why both and have the same measurements, its because they are Alternate Exterior Angles, based on the diagram shown.
Answer:
(4) 0
Step-by-step explanation:
<u>Given:</u>
- cos²27°×cos²34°×...×cos²167 = ?
<u>Looking at the angles measures, they form series of: </u>
This is AP with the first term of 27 and common difference of 7
<u>We can see one of the terms of this AP is 90</u>
Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.
<u>So correct answer choice is</u> Option 4) 0
