Step-by-step explanation:
Answer:
45.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship ...
Sin = Opposite/Hypotenuse
Filling in the given information, you have ...
sin(V) = 6.6/9.2
V = arcsin(6.6/9.2) ≈ 45.8395°
∠V ≈ 45.8°
_____
It can help to draw a diagram of the triangle, so you can see the letter designations of adjacent and opposite sides and the hypotenuse.
Answer:
y - Q = -5/2(x - P)
Step-by-step explanation:
The equation of a line in point slope form is expressed as y - y0 = m(x-x0)
(x0, y0) is the point
m is the slope
Given the equation
y = 2/5x− 4.
Slope m = 2/5
Slope of the perpendicular line = -1/(2/5) = -5/2
Point;
x0 = P
y0 = Q
Substitute into the formula;
y - y0 = m(x-x0)
y - Q = -5/2(x - P)
This gives the required equation
