Since

, it follows that

where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so
10x15= 150
150/2= 75
Diagonal = 75
Answer:
x=6 , y=17
Step-by-step explanation
3x-1=2x+5
+1 -2x
x=6
plug in 6 for x to solve y
Answer:
3
Step-by-step explanation:
6*5=30
30/10=3
Answer:
x = -10
Step-by-step explanation:
Solve the equation by simplifying according to PEMDAS. Then use inverse operations to solve.
4(x+5) = 3(x-2) -2(x+2)
4x + 20 = 3x - 6 - 2x - 4
4x + 20 = x - 10
3x = -30
x = -10
