Answer:
1260
Step-by-step explanation:
First you will need to find the amount of sides of the polygon:
(After looking it is 9)
Each angle of the side of a nonagon is 140 degrees.
Multiply by 9 since you can make 9 triangles:
140 x 9 = 1260
Answer:
about 76.2°
Step-by-step explanation:
The geometry can be modeled by a right triangle with the given dimensions being the side opposite the angle (height = 33,500 ft) and the side adjacent to the angle (8,200 ft). The fact that you know these two sides suggests the inverse of the tangent function may be useful.
Tan = Opposite/Adjacent
tan(angle) = (33,500/8,200)
angle = arctan (335/82) ≈ 76.246°
The angle of elevation is about 76.2°.
0.5(5-7x)=8-(4x+6)To start distribute the 0.5 and the negative to get 2.5-3.5x=8-4x-6
minus the 6 from the to get 2.5-3.5x=2-4x
subtract the 2 from both sides (it doesn't matter what side you choose to leave the x on when you solve, you will still get the same answerI) to get 0.5-3.5x=-4x
add the 3.5 to both sides to get 0.5=-7.5x
divide by -7.5 to get x=-0.066666666
Hi,
Here, the given question is incomplete. The equation for first line should be given.
Concept: The equation of a line having slope 'm' and intercept at 'c' to the y-axis is given as
y= mx +c -------(i)
If there is an other line which is parallel to given line then the slope of second line will be same.
Now, we are helping you by considering this question.
Find the slope of a line which is parallel to the line having equation 4x +y -5 = 0
Solution:
Step-01: we shall translate the given equation in to y = mx +c and find its slope.
Step-02: 4x+y - 5 =0 can be written as y = - 4x +5
Step-03: The slope of given line m = - 4
Step-04: The slope of required line which is parallel to the given line will be - 4. (by using the given concept of parallel property)
Hence, the given option (a) - 4 will be correct.
