The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
Hello there!
You're given the value of -109.3°F, and you are told that is 184.9°F less than the outside temperature. To find the outside temperature, add the difference to the temperature of dry ice.
-109.3°F + 184.9°F =75.6°F
So, the outside temperature is 75.6°F. I hope this was helpful, have a great rest of your day!
I see the cosine in problem 7 and I see the cotangent in problem eight. So I know that you're talking about trig functions in class. Problem 9 is trying to find out if you know what they're good for. You have a right triangle and you know the lengths of all three sides. So you can easily find the sine or the cosine or the tangent or the cotangent of the angle. Pick one and calculate the number. Then use your calculator to find the angle that has that number for the trig function that you chose.
