Answer:
the opposite Angles sum up to give 180
Step-by-step explanation:
3y +3y = 180
y=30
if y = 30 the x = 55
are you clear?
The numerator and denominators will have no common factors.
For example 4/6 is not in its simplest form because both 4 and 6 can be divided by 2. In simplest form this will be 2/3.
Answer:
y= -3/4x +5
Step-by-step explanation:
formula: y=mx+b
m= slope
x= variable
b= y-intercept
plug in the numbers into the formula.
y= -3/4x +5
Answer:
6.12
Step-by-step explanation:
tan 27≈0.51
