Answer:
income=2*expenses-100
Step-by-step explanation:
income=a*expenses+b
a:slope
a=(income of 1 - income of 0)/(expenses of 1 - expenses of 0)
=(10-0)/(55-50)=10/5=2
income=2*expenses+b
for product 0
income=0
expenses=50
》0=2*(50)+b
b=-100
income=2*expenses-100
The sum of the 3 inside angles need to equal 180.
You know 2 of the angles: 90 and 39
The third angle is 180 - 90 - 39 = 51 degrees.
Side a is given as 24
Side B = tan(39) = b/24 = 19.43 (round as needed)
Side C = cos(39) = 24/c = 30.88 (round as needed)
