Answer:
x= 60.1 degrees
Step-by-step explanation:
The triangle forms a right angle triangle
Opposite side of angle x = 13 ft
Hypotenuse of the triangle = 15
We know the opposite side and the hypotenuse
So we use trigonometric formula sin(x)
When we move 'sin' to the other side it becomes 'sin^-1'
x = 60.073565
-1 and 4 are the x-intercepts
2 and -2 are the y-intercepts
Answer:
<em>x = 64.5 feet</em>
Step-by-step explanation:
<u>Equations</u>
An isosceles triangle has two sides of the same length and one of different length.
The fence has the shape of an isosceles triangle with a base of 61 feet. The base is the side with a different length.
Call x to the length of each of the equal sides. Since the perimeter is the sum of all three sides, and the perimeter is given as 190 feet, then:
x + x + 61 = 190
Simplifying:
2x + 61 = 190
Subtracting 61:
2x = 190 - 61 = 129
Dividing by 2:
x = 129/2
x = 64.5 feet
120 a month (1250-650 = 600, 600 divided by 5 = 120)
