Answer:
The missing angle 'x' is 22.29°.
i.e. 
Step-by-step explanation:
Let 'x' be the missing angle of the triangle.
Using the formula
tan x = opp ÷ adjacent
tan x = 30 ÷ 72
tan x = 0.41


Therefore, the missing angle 'x' is 22.29°.
i.e. 
Answer: the correct answer is 175 - 0.23(175)
Step-by-step explanation:
Answer:
6 : 5
Step-by-step explanation:
Volume of a cube = s^3
5^3 = 125
Surface area of a cube = 6s^2
6(5^2) = 6(25) = 150
150 : 125
30 : 25
6 : 5
