Answer:
Ф = ------------ = 7/5 radians
Step-by-step explanation:
"e" is inappropriate format here. Use Ф or α or similiar character for central angle.
Here, (arc length) = (radius)(central angle), or s = rФ, and so:
(central angle) = Ф = (arc length) / (radius)
7 ft
Here, Ф = ------------ = 7/5 radians
5 ft
Answer:
<h3>The slope is -1.</h3>
Step-by-step explanation:
To find an equation of the line that passes through the points, you have to use the slope formula.
Slope:
y2=3
y1=(-2)
x2=(-1)
x1=4
Solve.
3--2/-1-4=5/-5=-1
The slope is -1.
Answer:
80°=x°[by alternate exterior angle]
To find the diameter, you use the formula: 2x. we use 2x because the radius is 2 times the diameter.
so, if the radius is 3,980, then we substitute that into the formula.
2(3,980)
this will give us 7960. the diameter is 7960 miles.
Answer:
x=4
Step-by-step explanation:
ABCD is a rectangle, so AD and BC are parallel. Thus, The angle complementary to 6x+19 is 47.
6x+19+47=90
6x+66=90
6x=24
x=4
