Answer:
3
Step-by-step explanation:
Basically, you need to calculate "x" correct?
The tangent of (52) = x / 20
1.2799 = x / 20
x = 1.2799 * 20

The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
The range for Week 1 equals he range for Week 2 is the true statement.
Answer: Option A.
<u>Step-by-step explanation:</u>
Median is the middle number of an ordered list.
75 is the median for Week 1 and Week 2.
The range is the difference between highest and lowest value for the given number series.
The highest and lowest value of the series for both Week 1 and Week 2 is same.
Lowest value =62.
Highest value =89.
∴ The range for Week 1 and Week 2 = 89-62.
The range for Week 1 and Week 2 = 27.
∴The range for both Week 1 and Week 2 remains the same.
Answer:
3a + 5b - 2
Step-by-step explanation:
The perimeter is the sum of all 3 sides of the triangle.
To find the missing side (x ) sum the 2 known sides and subtract from the perimeter.
x = 6a + 2b - 5 - (2a + 6b - 6 + a - 9b + 3 ) ← simplify parenthesis
= 6a + 2b - 5 - (3a - 3b - 3 ) ← distribute by - 1
= 6a + 2b - 5 - 3a + 3b + 3 ← collect like terms
= 3a + 5b - 2 ← length of missing side
