Answer:
r = -7
Step-by-step explanation:
-4 + 2r - 5r = 17
=> 2r - 5r = 17 + 4
=> -3r = 21
=> r = 21/(-3)
=> r = -7

Step-by-step explanation:
Answer: Exact value of sinθ in simplified form is 66.8° .
Step-by-step explanation:
Since we have given that
(-3,7)=(x,y)
As the terminal side of f θ passes through the point (−3,7)
So, Perpendicular will be =7 units
Base = 3 units
Since we know that
Hence, exact value of sinθ in simplified form is 66.8° .
Answer:
r = 19.0
s = 17.7
Step-by-step explanation:
In the given right triangle ABC,
Measure of Hypotenuse (AC) = 26
m(∠CAB) = 43°
By applying sine rule in the given triangle,
sin(43)° =
sin(43)° =
s = 26[sin(43)°]
s = 17.73
s ≈ 17.7
Similarly, by applying cosine rule in the given triangle,
cos(43)° =
=
r = 26[cos(43)°]
r = 19.02
r ≈`19.0
