Step-by-step explanation:
Answer:
A
Step-by-step explanation:
sin57° = 
= 
= 
∠ P = 180° - (90 + 57)° ← sum of angles in triangle
∠ P = 180° - 147° = 33° , then
cos33° = 
= =
Thus the 2 ratios used to solve for x are A
There are 3 terms : 7x , 4y, and 1.
a term is separated by any math symbol
examples are =, +, *
Answer:
y = (1/5)x - 8
Step-by-step explanation:
It's slope-intercept form y=mx+b and we just substitute m=1/5, b= -8.
