Step-by-step explanation:

The indicated side of the triangle is 17√2 unit.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

The triangle is a right-angled triangle.

The length of the perpendicular = 17 unit.

Two angles of the triangle are 45° and 45°.

That means, base = 17 unit.

And the triangle is an isosceles triangle.

By the Pythagoras' theorem,

a = √(289 + 289)

a = √578

a = 17√2 unit.

Therefore, the value of a is 17√2 unit.

Answer:

[tex]\frac{y}{x}[/tex], the fourth option.

Step-by-step explanation:

Tan means [tex]\frac{opposite}{adjacent}[/tex] or opposite side divided by adjacent side.

Tan A equals the opposite side of the angle A divided by its adjacent side.

The side opposite of A is y and side adjacent to it is x.

So, Tan A equals [tex]\frac{y}{x}[/tex]!

Answer:

The size of the sample 'n' = 2401

Step-by-step explanation:

Step:1

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

              [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

we know that the proportion

               [tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]

Step:2

The margin of error is determined by

              [tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]

              [tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

Final answer:-

The size of the sample 'n' = 2401

Answer:

132

Step-by-step explanation:

The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180

This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180

So x = 180 - 48

180 - 48 = 132

Hence, x = 132

Step-by-step explanation:

Answer: The median is 28208 the mean is 28234.6

Step-by-step explanation:

The mode is the number that is repeated the most there can be more than one mode.

Answer:

All in ft

Mean: 28,235

Median: 28,208

Range: 1,245

Step-by-step explanation:

Mean is the sum of the elements divided by the number of elements.

(29035+28250+28208+27890+27790)/5 = 28235

Median is the element in the exact middle of the set (if there is an even number of elements, take the average of the two elements in the middle).

After rearranging the numbers, we can see 28208 is in the exact middle.

27790 27890 28208 28250 29035

Range is the difference between the smallest and largest number in the set.

29035-27790=1245

Answer:

The orange moves at 2M/s

5/2.5=2

2meters/secon

The average speed of the orange is 2 m/sec.

Given that, orange falls off a display at a store and rolls 5 meters in 2.5 seconds.

We need to find the average speed of the orange.

Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speeds, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.

The formula for average speed is given as:

Average Speed = Total distance covered ÷ Total time taken

Now, average speed=5/2.5=2 m/sec.

Therefore, the average speed of the orange is 2 m/sec.

AB=c=20ft

<A=115°

By using Cosine rule.

a²=b²+c²-2bc cos angle

a²=30²+20²-2*30*20 Cos 115°

a²=1807.1419

a=√[1807.1419]

Formula: [tex]\frac{a+b}{2}[/tex] × h

---------------------------------------------------------------------------------------------------------------

Have a good day :)

Answer:

h = [tex]\sqrt{55}[/tex] in

Step-by-step explanation:

A right triangle is formed by h, slant height and radius

Here the legs are h and 6 ÷ 2 = 3, hypotenuse is 8

Using Pythagoras' identity in the right triangle

h² + 3² = 8²

h² + 9 = 64 ( subtract 9 from both sides )

h² = 55 ( take the square root of both sides )

h = [tex]\sqrt{55}[/tex] in
