Answer:
x= 30
The angles measure 80 degrees
Step-by-step explanation:
The two angles are corresponding angles and, when the lines are parallel, corresponding angles are equal.
2x+20 = 3x-10
Subtract 2x from each side
2x+20-2x = 3x-10-2x
20 = x-10
Add 10 from each side
20+10=x-10+10
30 = x
2x+20 = 2(30) +20 = 60+20 = 80
Answer:
no figure 1 isn't similar to figure 2
Step-by-step explanation:
because its sides aren't the same numbers nor do the numbers correlate with the numbers in figure one its 2 different numbers
The initial value of the graph is 7.
Actual:
15 ft wide and 10 ft high.
Area = 15ft * 10ft
Area = 150ft²
Scale drawing.
Every 16 inches represent 5 feet in the back drop.
15ft ÷ 5ft = 3 * 16 inches = 48 inches
10ft ÷ 5ft = 2 * 16 inches = 32 inches
Area = 48 in * 32 in
Area = 1536 in²
Area of the scale drawing is 1,536 square inch.
Answer:
23.84 feet
Step-by-step explanation:
Solving this question above, we using Trigonometric function tangent = Opposite/Adjacent
Opposite side + h = Height of the tree
We are told that:
A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50 degree angle of elevation. His eyes are 5 feet above the ground.
20 feet = Adjacent side = Distance form the tree
tan 50 = (h+5)/20
Cross Multiply
h + 5 = 20 × tan50
h = 20tan50 - 5
h= 18.835071852
h =18.84
Therefore the height of the tree is calculated as:
18.84+5 feet
=23.84 feet
