Answer:
Step-by-step explanation:
u = 45
v = 30
Angle between them, θ = 5π / 6 = 150°
(a) The formula for the dot product is given by



(b) 



Let the angle between them is θ
The formula in terms of the dot product is given by





θ = 75°
(c) 




Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get

It can be written as

The required equation is
.
Therefore, the correct option is B.
Answer:3
Step-by-step explanation:
Answer:
m /_ 1 is the same as m /_ 4 because they are vertical angels which equals to 35 degrees.
aince g and i are parallel :
m /_ 4 must equal m/_ 12 because they are exterior angels.
So the answer is 35 degrees
