Answer:
= cos4x
Explanation:
cosAcosB = [cos(A-B)+cos(A+B)]
Given: 2cos(2x)cos(2x)
= 2[cos(2x-2x)+cos(2x+2x)]
= 2cos4x^2
Answer: The probability would be 1/3.
Step-by-step explanation:
Answer:
<em>64 degrees</em>
Step-by-step explanation:
When you have the SRQ angle, you can easily solve for PQR. Luckily, we're given that QRP and PRS are 32 and 84, respectively. Adding this together gives you 116. 116*2 = 232 and 360-232 = 128, and 128/2 = 64.
