Answer:



Step-by-step explanation:
From the picture attached,
(8, -3) is a point on the terminal side of angle θ.
Therefore, distance 'R' from the origin will be,
R = 
R = 
= 
= 
Therefore, Cosθ = 
Sinθ = 
tanθ = 
Cscθ = 
1. -7(6v+4)+3v(v+3)
-42v-28+3v ²+9v
-33v-28+3v ²
=3v ²-33v-28
2. -3k(2k-3)+7(k-7)
-6k ²+9k+7k-49
= -6k ²+16k-49
Answer:
15°C
Step-by-step explanation:
Use the following formula to convert Fahrenheit to Celsius:

Substitute the value for the variable and solve for C.

Therefore, 59°F is equivalent to 15°C.
