Answer:
1. x = -6, -8, -90
2. solutions for include -5, while -5 is not a solution for
Step-by-step explanation:
33.3 repeating
This can be simply found out by dividing 3.75 from 1.25
1.25 / 3.75 = .33
Mangoes = 4/9 x 180 = 80
Oranges = 5/9 x 180 = 100
Bananas = 3/9 x 180 = 60
Bananas:mangoes:oranges = 3:4:5 = 60:80:100
Total number of fruit = 60 + 80 + 100 = 240
Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
cos(x) =
cos(x) =
x =
x = 25.84
x ≈ 25.8°
12). By applying tangent rule in the given triangle,
tan(x) =
tan(x) =
x =
x = 67.29°
x ≈ 67.3°
