What is the length of the altitude of the equilateral triangle below?

Option B =6.

Step-by-step explanation:

In any equilateral triangle the three angles are of equal measure and they equal 60 degrees.

When we drop a perpendicular that is height of triangle a we have a 30 -60 90 triangle .In any 30 -60 -90 triangle the sides are in the ratio 1:√3:2

In the given triangle the longer leg that is the side opposite to 60 degree angle represent the height of the triangle.THe side opposite to 30 degrees is the shorter leg We can find the long leg by multiplying the short leg by the square root of 3.

Altitude of triangle=2√3(√3)=2(3)=6.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
