Answer:
relationship between base and hypotenuse is given cos angle
cos 20=b/h
cos20=x/160
x=cos20×160=150.35=150ft is your answer
Step-by-step explanation:
try yourself
know the basic concept
1/2 times 10 is 10/2 but it reduces to 5. Last ones are 2/15 and 1/6
Answer:
The polygon with the smallest perimeter is the megagon
The polygon with the largest perimeter is the triangle
Step-by-step explanation:
An equilateral triangle with area = 20 has
0.5× a²×sin60 = 20
a= 6.796
Hence, perimeter = 20.39
A square of area 20 has perimeter= 4×√20 = 17.9
A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05
Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases
Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.
Quadratic refers to x^2 so the quadratic formula can be used to solve an equation only at the highest degree in the equation is a two/squared
It is c. If you do the equation it is -1 1/4
