Answer:.3
Step-by-step explanation: if it is 5 or above it rounds up
It's a linear function: y = mx + b
We have (138; 112.96); (209; 142.78)
substitute the values of x and y to the formula of slope m:
Now we have: 
We must find b. Substitute the value of x and y from first pair of numbers:
Answer: y = 0.42x + 55
On the unit circle, the abscise (x) is the cosine and the ordinate (y) = sinus
So y is the sinus
Answer:
70° , 70°
Step-by-step explanation:
The 2 angles are corresponding and are congruent, then
23x + 1 = 4 + 22x ( subtract 22x from both sides )
x + 1 = 4 ( subtract 1 from both sides )
x = 3
Then the angles are
23x + 1 = 23(3) + 1 = 69 + 1 = 70°
4 + 22x = 4 + 22(3) = 4 + 66 = 70°
