The answer is A. y = [x] -2
From the given, we can say that the shorter door covers that amount with 2/5 of it overlapping the large door. So 3/5 of it is 36 inches long. Setting up a proportion: 3/5 = 36/x
3x = 180
x = 60 So from this, the shorter door is 60 inches long. The longer door is 60 inches plus 1/2 of the original overlap. Original overlap is calculated by = 60 - 36 = 24 So the longer door is calculated as: (60 + 12) 72 inches. So the width of the cabinet is the longer door + the amount it doesn't cover. So computing for the width will give us: 72 + 36 = 108 inches
First,B bisects AC, this means that B dovids AC into two equal halves. therefore AB=AC
second and third steps are just isolating the terms containg y on one side of the equation and the other terms on the other side.
finally you have 3y=15, to get the value of y,you divide both sides of the equation by 3.
Answer:
- The scientist can use these two measurements to calculate the distance between the Earth and the Sun by applying one of the trigonometric functions: Cosine of an angle.
- The scientist can substitute these measurements into and solve for the distance between the Earth and the Sun.
Step-by-step explanation:
Let's assume that the right triangle formed is like the one shown in the figure attached, where "d" represents the distance between the Earth and the Sun.
Then:
The scientist can use only these two measurements to calculate the distance between the Earth and the Sun by applying one of the trigonometric functions: Cosine of an angle.
The scientist can substitute these measurements into , and solve for the distance "d".
Knowing that:
Then:
And solving for "d":
Straight line = 180 degrees so angle opposite a = 180-128 = 52
then triangle adds up to 180 degrees so a= 180-52-73 =55 degrees
