Answer:
1.6 hours
Step by step explanation;
1 hour would make them only 150 miles apart, 60% of 120 and 60% of 130 added together is 150 mph, so 1.6 hours
Hope this helps :)
Answer:
A. √3 : 2
D. 3√3 : 6
Step-by-step explanation:
In a triangle described as 30°-60°-90° triangle, the base angles are 90° and 60°
The side with angles 90° and 60° is the shortest leg and can be represented by 1 unit
The hypotenuse side is assigned a value twice the shorter leg value, which is 2 units
From Pythagorean relationship; the square of the hypotenuse side subtract the square of the shorter leg gives the square of the longer side
This is to say if;
The given the shorter leg = 1 unit
The hypotenuse is twice the shorter leg= 2 units
The longer leg is square-root of the difference between the square of the hypotenuse and that of the shorter leg

where the longer leg is represented by side b in the Pythagorean theorem, the hypotenuse by c and the shorter leg by a to make;

<u>Hence the summary is</u>
a=shorter leg= 1 unit
b=longer leg = √3 units
c=hypotenuse=2 units
The ratio of longer leg to its hypotenuse is
=√3:2⇒ answer option A
This is the same as 3√3:6 ⇒answer option D because you can divide both sides of the ratio expression by 3 and get option A

Answers are :option A and D
Answer:
4
Step-by-step explanation:
(-3) * (8/-6)
3 * 8/6
3 * (2 * 4)/6
3 * (2 * 4)/(2 * 3)
3 * (4/3)
4
Answer:
PV = 8 VT = 4√3
Step-by-step explanation:
Given
PT = 4
With reference angle 30°
perpendicular (p) = 4
hypotenuse (h) = ?
sin 30° = p/h
1/ 2 = 4 / h
cross multiply
h = 8
with reference angle 60°
perpendicular (p) = ?
hypotenuse (h) = 8
sin 60° = p/h
√3 / 2 = p / 8
Cross multiply
2p = √3 * 8
p = 4 √3
