Step-by-step explanation:
In an equilateral triangle, all the three sides are equal as well as all the angles are equal. Let the angles be x.
We know that the sum of angles of a triangle is equal to 180 degrees. It means that,
x+x+x=180
3x=180
x=60°
Hence, if a triangle is an equilateral triangle, then the triangle has exactly three 60° angles. Hence, △ABC is an equilateral triangle
Answer:
7 seconds
Step-by-step explanation:
Distance of the coin above the water is modeled by the equation
where 
is time taken to cover the distance
Now equating with zero.
So, time taken by the coin to hit the water is 7 seconds.
Hello there,
The answer will be <u>1</u><u>5</u><u> </u><u>students.</u>
<h3>Step-by-step explanation:-</h3>
We will solve the equation as follows:-
First add the total of the students in band and chorus -
→ 70 + 95 = 165
Then subtract the previously got number with given number of chorus students:-
→ 165 - 150 = 15
So, there are <u>15 students</u> who are there in both band and chorus.
