Answer:
Step-by-step explanation:
triangle ABC is an equilateral so all angles and sides are equal to each other
AB = 6
triangle DEF is an isosceles so two of its angles are equal to each other
a triangles angles add up to 180°
to find the measure of these angles we’ll write this equation:
x + x + 40 = 180
and solve for x
2x + 40 = 180
2x = 140
x = 70°
so mF is 70°
The length of the shadow is 14.2 m
Right angle triangle:
Right angle triangle has one of its sides as 90 degrees.
The height of the building is the opposite side of the triangle.
The distance from the top of the building to the tip of the shadow is 35 m is the hypotenuse side.
The length of the shadow is the adjacent side of the triangle.
Therefore,
c² = a² + b²
b² = 35² - 32²
b² = 1225 - 1024
b² = 201
b = √201
b = 14.17
b = 14.2 m
Hence the length of the shadow is 14.2 m.

Answer:
y = -2(W - x + 2)
Step-by-step explanation:
W=x-y/2- 2
W - x + 2 = - y/2
-2(W - x + 2) = y
What is the slope of the line parallel to y = 3x + 7?
the slope of the line parallel is the same
m= 3
Find the slope of the line 2x + 5y = 10
solve for y
subtract 2x from each side
5y = -2x +10
divide by 5
y =-2/5 x+2
slope is -2/5
Find the vertex of the following absolute value equation.
y = -1/2|5x+2|-3
the x coordinate of the vertex is
5x+2 =0
5x=-2
x= -2/5
the y coordinate of the vertex is -3
(-2/5, -3)
