Answer:
7.43
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:
-37/5= y
x=11/5
Step-by-step explanation:
4x-3y=31
-3y=-4x+31 regroup it to match the other
-2 y=(2x-3)(-2) multiply by -2 to get -4x
-3y=-4x+31
-2y=-4x+6 adding
-5y=37 divide
-37/5= y
4x-3(-37/5)=31
x=11/5
