Answer:
83.9°
Step-by-step explanation:
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
a= 13 cm
a2= 169cm
b= 4cm
b2=16 cm
a2+b2= 185cm (c2)
c=13.6cm
after wards use the law of cosines and c= 83.9°
what type of help you need
-G + 15 = - 2G + 23
- 15 -15
-G = -2G + 8
+2G +2G
S0, G = 8 is the answer
6 workers
Number workers to earnings is direct proportion.
8: 2400 :: x : 1800
Product of means = Product of extremes
2400 * x = 8*1800
38.888 It is only divided with a calculator. my answer is useful
