40%
20%
5%
80%
Answer:
40
Step-by-step explanation:
divide both by 2
40 percent of 100 is 40
or
80/200 = .4 or .40 which is 40%
Answer:A1 = a If A1 represents a variable in an equation, we need the equation and any additional information to solve for its value. Once we have the equation and any given values, we can substitute those values into the equation and solve for A1. Without more context or information, it is not possible to determine the value of A1. If you can provide the equation or any additional details, I will be able to help you further in determining the value of A1.
Step-by-step explanation:
B) 70°
C) 90°
D) 120°
Answer: A)
Step-by-step explanation:
Given: ΔABC is similar to ΔDEF
Therefore,
∠A=∠D=50°
∠B=∠E=70°
∠C=∠F
Using Angle sum property, in triangle ABC, we get
The angle sum property of a triangle says that, the sum of all the angles in a triangle is .

To find the height of the tree, we can use trigonometry and the given information.
Let's denote the height of the tree as h.
1. We have the length of the shadow, which is 150 ft.
2. We also have the angle of elevation from the tip of the shadow to the top of the tree, which is 30°.
We can use the tangent function to find the height of the tree:
tangent(angle) = opposite/adjacent
In this case, the opposite side is the height of the tree (h) and the adjacent side is the length of the shadow (150 ft).
So, we can write the equation as:
tangent(30°) = h/150
Now, let's solve for h:
tangent(30°) = h/150
tan(30°) = h/150
√3/3 = h/150
Cross-multiplying:
3h = 150√3
h = 50√3
To find the approximate value, we can use a calculator:
h ≈ 50 * 1.732 ≈ 86.6 ft
Rounded to the nearest foot, the height of the tree is approximately 87 ft.
Therefore, the correct answer is option B: 87 ft.
