Answer:
1 = 56°
Explanation:
Interior angles 1 and 83° must add up to the external angle 139° because of the reason ‘exterior angles of a triangle’.
Angle 1+83°=139° (ext angles of triangle)
Angle 1 = 139°-83°
Angle 1 = 56°
The resulting triangle is a right triangle with the third side given:
First, the angle can be solved using the given rise and run of the cable. So,
tan θ = 2 / 5
θ = 15.95°
Next, the lengths b and c can be solved using the solved angle:
tan 15.95 = 1320 / b
b = 3300 ft
The hypotenuse or c can be solved by trigonometric functions or using Pythagorean theorem, using the sine function:
sin 15.95 = 1320 / c
c = 4804 ft
If these are all separate answers, then: y=3r-1
Substitute r for the value it's asking for.
R=-1
y=3(-1)-1
(Answer) y=-4
R=-8
y=3(-8)-1
y=-24-1
(Answer) y=-25
R=-4
y=3(-4)-1
y=-12-1
(Answer) y=-13
R=2
y=3(2)-1
y=6-1
(Answer) y=5
R=6
y=3(6)-1
y=18-1
(Answer) y=17
