Answer:
Step-by-step explanation:
Area = height * length
Let length of mural be x so height is 2/3x
Area = 2/3x*x = 600
x*x=900
x=30 feet
Length = 30 feet
Height = 2/3 *30 = 20 feet
Answer:
Step-by-step explanation:
Since this is a right triangle, we will use a right triangle trig identity to solve our problem. The side opposite the reference angle A is given as 5, and the side adjacent to the reference angle is given as 7. The trig ratio that uses the sides opposite and adjacent is the tangent ratio:

Hit the 2nd button on your calculator then the tan button which displays:

Enter 5/7 after that open parenthesis and hit = to get that
A = 35.54°

This question is soooo easy
Step-by-step explanation:
(3x)^2+(5)^2+2.3x.5
9x^2+25+30x
Answer:
x = 66
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
