Answer:
x= 105
y= 40
Step-by-step explanation:
3y=4y-40 because they are alternate interior
Solve for y.
y=40
4y-40=x+15 because they are vertical angles.
Substitute 40 in for y.
4(40)-40=x+15
Solve.
x=105

bit.
6 × 2 = 12 so 6 is the dilation factor
thus 4 × 6 is PQ which is 24
The system should look like this:
eh + b = 243
eh - b = 109
Answer:
cos 225° = 
sin 225° = 
tan 225° = 1
Step-by-step explanation:
I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45° (225 - 180 = 45)
cos and sin are negative in the 3rd quadrant and the tan is positive
cos 225° = - cos 45° = 
sin 225° = -sin 45° = 
tan 225° = tan 45° = 1
