There are buttons on all scientific calculators for inverse trig functions.

Usually denoted as "arcsin, arccos" or with a little -1 inverse sign like this:
 sin^{-1} (0.2588) = 14.99

You put in the measurement and it gives back the angle. I

angle x = 15°

complimentary angles add up to 90° so the angle that's complimentary is 90-15 = 75°

PV = 8 VT = 4√3

Step-by-step explanation:

Given

PT = 4

With reference angle 30°

perpendicular (p) = 4

hypotenuse (h) = ?

sin 30° = p/h

1/ 2 = 4 / h

cross multiply

h = 8

with reference angle 60°

perpendicular (p) = ?

hypotenuse (h) = 8

sin 60° = p/h

√3 / 2 = p / 8

Cross multiply

2p = √3 * 8

p = 4 √3

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except -3. Which
Maurinko [17]

Answer:

The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Step-by-step explanation:

As the domain of f(x) is the set of all real values except 7. So it can be written as follows:

              Domain of f(x) = { x ∈ R | x ≠ 7}

As the domain of g(x) is the set of all real values except -3. So it can be written as follows:

              Domain of g(x) = { x ∈ R | x ≠ -3}

It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.

So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Keywords:  domain, composite function

How would i find the measurement of angle 1 &amp; 2
tatyana61 [14]

Check the picture below.

keeping in mind that a circle has a total of 360°, if the twin angles of 72°  add up to 144°, what remains for the other twin angles is 360° - 144° = 216°, and that 216 is split between both twins for 108 a piece, taking away the 40° next to ∡2, gives us ∡2.
