2 angles whose sum is 180 are supplementary angles
Angle TRQ is 23 degrees and the length from S to R is 3.3 units.
I need help on this too
Answer:
The current temperature on the X scale is 1150 °X.
Step-by-step explanation:
Let is determine first the ratio of change in X linear temperature scale to change in Y linear temperature scale:



The difference between current temperature in Y linear scale with respect to freezing point is:


The change in X linear scale is:



Lastly, the current temperature on the X scale is:


The current temperature on the X scale is 1150 °X.
Answer: sec (75) or csc (15)
Step-by-step explanation:
255 is in the 3rd quadrant where the secant is. Here, the tangent and cotangent is positive.
Reference angle for 255 is,
255 - 180 = 75 degrees.
Therefore, sec (255) = sec (75)
= csc (90 - 75) = csc (15)
