<h3>Question:- What is the measure of A?</h3>

<h3>Given :- </h3>

With respect to the diagram in question

Angle A = (3x-13)°
Angle B = (2x+4)°
Exterior Angle C = 116°

<h2>Answer:- </h2>

Exterior Angle property

Exterior angle of triangle is equal to sum of two opposite interior angle .

$\angle{A} + \angle{ B} = ext \angle C \\ putting \: the \: value \\ 3x - 13 + 2x + 4 = 116 \\ 5x - 9 = 116 \\ 5x = 125 \\ x = \frac{125}{5} \\ x = \frac{ \cancel{125} {}^{ \: \: 25} }{ \cancel5} \\ x = 25$

For Angle A :- 3x-13

$\angle A = 3x-13 \\ \angle A = 3(25)-13 = 75 - 13 \\ \angle A = 62 \degree$

In order to determine Velocity, we need to know.. *

Gennadij [26K]

Answer:

All of the above.

Step-by-step explanation:

The way to calculate velocity is d/t, the displacement over time of travel. Hence, both of those are needed.

Finally, velocity also needs to know your direction, like 5 m/s East for example. Hence, all of the above are needed.

Hope this helped!

Hal has a steel barrel with a diameter of 6 feet that can be filled to a depth of 4.6 feet with oil. What is the volume of the b

scoray [572]

Answer:

129.996 cubic feet

Step-by-step explanation:

Assuming that the barrel is a perfect cylinder, we can use the formula to find the volume:

$\pi(r)^2(h)$

First, we have to find the radius, which is:

D = 2r

So the radius is 3 feet, since it is half of the diameter. Then, we plug in the values.

$3.14(3)^2(4.6)$

Now, we solve. Exponents are first...

3.14(9)(4.6)

Now multiply left to right.

28.26(4.6)

129.996 cubic feet

Therefore, the barrel can hold 129.996 cubic feet of oil. Hope this helps you!
