Answer:
x= -3/4 + y/4
Step-by-step explanation:
Move all terms that don't contain
x to the right side and solve.
We have learned that, in in an algebraic expression, letters can stand for numbers. When we substitute a specific value for each variable, and then perform the operations, it's called evaluating the expression. Let's evaluate the expression 3y + 2y when 5 = y.
The answer to your question is: 60.3°
Data
height = 7 m
shadow = 4 m
angle = ?
Process
tangent Ф = opposite side / adjacent side
tangent Ф = 7 / 4
tan Ф = 1.75
Ф = 60.3°
