I got B but I'll show you how I got that answer.
Let's look at AB and BC. AB = 3 and BC = 4.
3/4 = 0.75
On the triangle, AB = 90. And BC = 10x - 20. We need to solve for x and prove that AB/BC = 0.75.
Let's start with Choice A.
10(11) - 20 = 90.
AB = 90
BC = 90.
90/90 = 1. It doesn't equal 0.75. Meaning this answer is wrong.
Now let's look at Choice B.
10(14) - 20 = 120.
AB = 90
BC = 120
90/120 = 0.75
So, 3:4 = 90:120 making Choice B the correct Answer. Let me know if this is correct
We divide when converting pints to quarts because pints are smaller units of measurements than quarts, so when converting pints to quarts, our answer will be getting smaller. This is because 2 pints= 1 quart, so since we are trying to find the amount of quarts that the pints can make up, we will always divide the pints by 2. (since 2 pints= 1 quart)
Answer:
66.5
Step-by-step explanation:
A=b•h/2
A=19•7/2 19•7=133
A=133/2 133/2= 66.5
A=66.5
The answer to this is C.17
The arrangement of mother's eye level, ground level and playground forms a right angles triangle.
The legs of this triangle are 12.6 m (eye level to ground) and 20 m (building to playground).
Using trigonometry and assuming the depression angle is Ф;
tan Ф = 20/12.6 = 1.5873
Ф = tan ^-1(1.5873) = 57.78°
