90/2=45
45/3=15
15/3=5
90=2*3*3*5=2¹*3²*5¹
Answer:
6√2.
Step-by-step explanation:
The two radii are equal length and form a right angle, so the resulting triangle is 45-45-90. Therefore, the length of the chord (the hypotenuse of the triangle) is 6√2.
Answer:
D). 2.4 
Step-by-step explanation:
Mary is driving toward north so the angle is 90° and Danny is driving toward the east so angle is 0°
Momentum Dary= 
Momentum Danny= 
So the total momentum is the magnitude:
Mag= 
mag=
