Answer:

Step-by-step explanation:

Answer:
Sec y = q/r
Step-by-step explanation:
Sin y = 7/q
tan y = 7/r
Mathematically cos y = sin y/tan y
But sec y = 1/cos y
So therefore sec y = tan y/sin y
So that would be ;
7/r divided by 7/q
= 7/r * q/7
= q/r
Answer:1.5
Step-by-step explanation:
(1,4) this is because the flip over y axis does not touch the y value but gives the opposite of the x value
