An electric car can travel at top speed for 107 km on 5 h charging time. If the car died after just traveling 65 km at top speed
Taya2010 [7]

Answer:

  C.)  3 h

Step-by-step explanation:

If you assume the distance is proportional to the charge time, then ...

  x/5 = 65/107

  x = 5(65/107) ≈ 3.04

The car may have held about a 3-hour charge.

vagabundo [1.1K]

Answer:

A=63.4\ ft^2

Step-by-step explanation:

we know that

The area of triangle applying the law of sines is equal to

A=\frac{1}{2}(a)(b)sin(C)

we have

a=9\ ft\\b=15\ ft\\C=110^o

substitute the given values

A=\frac{1}{2}(9)(15)sin(110^o)

A=63.4\ ft^2

Determine the measurement of angle 2<br> i need all angles from 2 to 8
SOVA2 [1]

Answer:

<1 = 112º

<2 = 68º (given)

<3 = 68º

<4 = 112º

<5 = 112º

<6 = 68º

<7 = 68º

<8 = 112º

Step-by-step explanation:

Supplementary angles add up to 180º. Once you find the measure of <1 and <2, the bigger angle will always be the bigger number and the smaller angle will always be the smaller number from <1 and <2.

There's a better way to explain it but you would need to go to the basics of all angle rules.
