Step-by-step explanation:
Using SOHCAHTOA
Second Question Explanation:
a. The base angles of an isosceles triangle are equal so angle ABC is also 32°
but the sum of angles in a triangle = 180° therefore
let angle CAB be x
b. If you share a triangle in half you get 2 right angles so I'll use SOHCAHTOA to find the length AB
First the base of the right angled triangle will be 20/2 = 10
c. To find the are we'll need to get the height first
using the right angled triangle With base 10cm and hypotenuse 11. 8 to find the height we'll use the Pythagorean theorem
now to find the area
Answer:
Answer is 12/13 B
Step-by-step explanation:
We are trying to find the average speed of the plane, which is mph, or . Using proportions, we can find the average speed of the plane in mph:
- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that .
- Multiply the entire equation by
- Divide both sides of the equation by to clear both sides of the mile unit
The average speed of the plane is 300 mph.
<u>Answer:</u>
Probability of getting three jacks =
<u>Step-by-step explanation:</u>
It is given that you deal three cards from a regular deck which contains 52 cards.
We are to find the probability of getting all three Jack cards.
We know that there are a total of 4 jacks in a regular deck of 52 cards.
Therefore, the probability of getting three jacks =
