Answer:
sin Ф = 3/√13; cos Ф = 2/√13; and tan Ф = 3/2
Step-by-step explanation:
Let's assume we're limiting ourselves to Quadrant I.
Start with the tangent function. tan Ф = opp / adj.
In this case opp = 3 and adj = 2.
The length of the hypotenuse is found using the Pythagorean Theorem and is √(3² + 2²) = √13.
Then sin Ф = opp / hyp = 3/√13 or 3√13/13
and
cos Ф = adj / hyp = 2/√13 or 2√13/13
and (as before)
tan Ф = opp / adj = 3/2
Answer:
m = 15
Step-by-step explanation:
to evaluate for the expression -7+m=8?
solution
-7+m=8?
collect the like terms
m = 8 + 7
m = 15
Answer:
4x + 4y
Step-by-step explanation:
<u>Step 1: Distribute</u>
4(x + y)
(4 * x) + (4 * y)
(4x) + (4y)
<em>4x + 4y</em>

Answer: 4x + 4y
Answer:
Graph A, because it includes y- intercept = 1 and the points (1, -2) and (-1,-2), which can be checked and verified in the equation.
Answer:
x = 15°
Step-by-step explanation:
The secant- tangent angle x is half the difference of the intercepted arcs, that is
x = 
(80 - 50)° = 0.5 × 30° = 15°
