i believe it is 173 and 145.
Answer:
perpendicular
Step-by-step explanation:
x = -2 is a vertical line at x = -2
y is a horizontal line the two lines are perpindicular
Standard form is y=Mx+b so first step is to isolate y:
Y=1/3(x+3)-11
Then use order of operations to simplify the x to a whole number. First multiply by three:
3y=x+3-33
Now combine like terms:
3y=x-30
Finally,
Divide to make y have a coefficient if one:
Y= 1/3x -10
Answer:
see the explanation
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional (this ratio is called the scale factor) and its corresponding angles are congruent
therefore
Two triangles are similar if there is a correspondence between their angles and their sides so that all corresponding angles are <u><em>congruent </em></u> and all corresponding sides are <u><em>proportional</em></u>
A coterminal angle of θ such that 0 ≤ θ ≤ 2π is equal to 7π/4 and the exact value of Sin(θ) = -1/√2.
<h3>What is a coterminal angle?</h3>
A coterminal angle can be defined as an angle that share the terminal side of an angle which occupies the standard position i.e it has the same initial side.
In this scenario, all angles that are multiples of 2π and added to the given angle (-9π/4) would be coterminal. For the range [0, 2π], 8π should be added to the given angle as follows:
Coterminal angle = -9π/4 + 4π
Coterminal angle = -9π/4 + 16π/4
Coterminal angle = 7π/4.
<h3>Part B.</h3>
The reference angle is given by:
7π/4 -π = 3π/4.
Therefore, the exact values of all six (6) trigonometric functions evaluated at θ are:
