Answer:
Cosθ =Adjacent / hypotenuse

Answer:c= a +b
Step-by-step explanation:
A) 13 degrees because it would be 90-77
If two angles are complementary, then the two angles add up to 90 degrees.
If angle A is 77, then the complement would be 90-77 or 13 degrees.
b) The complement of the complement of the angle is the angle itself.
Say the angle A is 30 degrees. It's complement is 90-30 or 60 degrees.
The complement of the 60 degrees is 30 degrees.
So the complement of the complement of the angle would be the angle itself.
Hope this helps :)
Assuming you meant 6x198 do a mental sum for 6x200 (1200) then subtract 6x2(12)to give you 1188
Answer:
The measure of SWX is 108.
Step-by-step explanation:
TX and QS are not perpendicular.
QRT and TRU are complementary (add to 90) not supplementary (add to 180)
The measure of SWX is 108 because angles on a line add to 180, and RWS is 72. 180 - 72 = 108
