Answer:
.2 miles per minute or .2x
Step-by-step explanation:
it move one tenth in half a minute so it moves 2 tenths in a minute.
A counterexample for the expression secФ / tanФ = sinФ is 45°
This is a FALSE statement.
Explanation:
Solving Right-hand side:
SecФ = 1 / CosФ
tanФ = SinФ / CosФ
secФ/tanФ = 1 / CosФ ÷ SinФ / CosФ
secФ/tanФ = 1 / CosФ × CosФ/SinФ
secФ/tanФ = CosФ / SinФCosФ
secФ/tanФ = 1 / SinФ
Hence,
Left-hand side ≠ Right-hand side
The side across from the 63° angle is 299.5 ft and the side across from the 56° angle is 278.7 ft.
We will use the Law of Sines to solve this. First, the angle across from the 63° angle:
sin 61/294 = sin 63/x
Cross multiply:
x*sin 61 = 294 sin 63
Divide by sin 61:
(x sin 61)/(sin 61) = (294 sin 63)/(sin 61)
x = 299.5
For the side across from the 56° angle:
sin 61/294 = sin 56/x
Cross multiply:
x*sin 61 = 294 sin 56
Divide both sides by sin 61:
(x sin 61)/(sin 61) = (294 sin 56)/(sin 61)
x = 278.7
Answer:
Step-by-step explanation:
Yes
It is correct
The line n intersects line m and at the point of intersection two angles are formed, which are 3x and x.
Please note that angles on a straight line equals 180 degrees. That means angle 3x and angle x both sum up to 180. This can be expressed as;
3x + x = 180
4x = 180
Divide both sides of the equation by 4 (to eliminate the 4 on the left hand side and isolate the x)
x = 45
