7x - 5 = 11
Step-by-step explanation:
To solve for x, substitute y = -5 into the equation 7x + y = 11.
This becomes 7x + (-5) = 11 or 7x - 5 = 11.
Step-by-step explanation:
use CAH method (Cos angle = adjacent/hypotenuse)
Given adjacent = 5
Hypotenuse = 12,
Answer:
x = 20.8
y = 22.3
Step-by-step explanation:
tan(21) = 8/x
or, x = 8/tan(21)
or, x = 20.8 (rounded to the nearest tenth)
sin(21) = 8/y
or, y = 8/sin(21)
or, y = 22.3 (rounded to the nearest tenth)
