Answer:
Step-by-step explanation:
1) the triangle is a right angle triangle.
From the given right angle triangle,
With 67° as the reference angle,
x represents the adjacent side of the right angle triangle.
17 represents the opposite side of the right angle triangle.
To determine x, we would apply
the Tangent trigonometric ratio.
Tan θ = opposite side/adjacent side.
Therefore,
Tan 67 = 17/x
xTan 67 = 17
x = 17/Tan 67
x = 17/2.3559
x = 7.22
2) From the given right angle triangle, with 24° as the reference angle,
x represents the opposite side of the right angle triangle.
12 represents the adjacent side of the right angle triangle.
To determine x, we would apply
the Tangent trigonometric ratio.
Tan θ = opposite side/adjacent side.
Therefore,
Tan 24 = x/12
x = 12Tan 24
x = 12 × 0.4452
x = 5.34
Answer:
8 1/12
Step-by-step explanation:
13 1/4 - 5 1/3 = (13-5) + (1/4 - 1/3)
= 8 + (4/12 - 3/12)
= 8 1/12

Step-by-step explanation:
Answer:
40% decrease
Step-by-step explanation:
First, let's find the value decrease of the item from yesterday to today
$65 - $39 = $26
That means that $65 was 100% of the price and decreasing it by 26 gets us to 39
We need to find the percentage of 39 in 65
39/65 = 0.6 or 60%
If 39 is 60% of 65, then there was a 40% decrease form 100%
To check we can calculate the percentage of 26 in 65:
26/65 = 40%
There was a 40% decrease
