Find the missing side. Round to
the nearest tenth.
Х
28°

x = [?]
Given:
The right triangle with base 15 and hypotenuse x.
The measure of angle between base and hypotenuse is 28 degrees.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
In the given triangle,
[tex]\cos 28^\circ=\dfrac{15}{x}[/tex]
[tex]x=\dfrac{15}{\cos 28^\circ}[/tex]
[tex]x=\dfrac{15}{0.8829476}[/tex]
[tex]x=16.98855[/tex]
Round the value to the nearest tenth.
[tex]x\approx 17.0[/tex]
Therefore, the value of x is 17.0 units.

Answer:
63. Perimeter: 60.4 units
Area: 126.14 units²
64. x = 8
m = 62⁰
Step-by-step explanation:
First, let us solve question 63. To find the perimeter and the area of the triangle, we will first find the x and y value.
Formulas we would use to find the answer in Q. 63 :-
Cos = opposite / hypotenuse
Sin = adjacent / hypotenuse
Area = 1/2 × b × h
Perimeter = adding all sides
Let us find the y value using the formula of Cos.
Cos = opposite / hypotenuse
Cos24⁰ = y / 26
26(Cos24⁰) = (y / 26)26
26(Cos24⁰) = y
23.8 = y ---> *since it said to round to the nearest hundredth.*
Now let us find the x value by using the formula of Sin.
Sin = adjacent / hypotenuse
Sin24⁰ = x / 26
26(Sin24⁰) = (x / 26)26
26(Sin24⁰) = x
10.6 = x ---> *since it said to round to the nearest hundredth.*
Now let us find the perimeter and the area.
Area = 1/2 × b × h
Area = 1/2 × 10.6 × 23.8
Area = 126.14 units²
Perimeter = adding all sides.
Perimeter = 26 + 23.8 + 10.6
Perimeter = 60.4 units
On to Q. 64. Formulas we would use to find the answer of Q. 64 is :-
Tan = opposite / adjacent
Sin = opposite / hypotenuse
Let us find m. In order to find m, we will use the Sin formula.
Sin = opposite / hypotenuse
Sinm⁰ = 15 / 17
m⁰ = sin-1(15 / 17)
m⁰ = 62 ---> *since it said to round to the nearest whole number.*
Now let us find x by using the formula of Tan.
Tan = opposite / adjacent
Tan62⁰ = 15 / x
x(Tan62⁰) = (15 / x)x
x(Tan62⁰) = 15
x(Tan62⁰) / Tan62⁰ = 15 / Tan62⁰
x = 15 / Tan62⁰
x = 8 ---> *since it said to round to the nearest whole number.*
Hope this helps, thank you :) !!

Step-by-step explanation:
The junior and senior classes at Central High School were asked to choose a destination for a field trip. The results are shown in the given two-way frequency table.
Central High School Field Trip Destination
Amusement Park Museum Broadway Show Total
Juniors 57 21 42 120
Seniors 64 44 58 166
Total 121 65 100 286
What percentage of surveyed students chose the amusement park?
A.
38.55%
B.
47.50%
C.
19.93%
D.
42.31%
Answer:
D) 42.31%
Step-by-step explanation:
If 121 people went to the amusement park out of 286 total students, then the percentage of surveyed students that chose the amusement park would be 121/286=0.4230769231=42.31%, making option D correct.
how to find 62%of $400
Answer:
248
Step-by-step explanation:
Solution for What is 400 percent of 62:
400 percent *62 =
(400:100)*62 =
(400*62):100 =
24800:100 = 248
Now we have: 400 percent of 62 = 248
Question: What is 400 percent of 62?
Percentage solution with steps:
Step 1: Our output value is 62.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$62=100\%.
Step 4: Similarly, x=400\%.
Step 5: This results in a pair of simple equations:
62=100\%(1).
x=400\%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
\frac{62}{x}=\frac{100\%}{400\%}
Step 7: Again, the reciprocal of both sides gives
\frac{x}{62}=\frac{400}{100}
\Rightarrow x=248
Therefore, 400 of 62 is 248
Answer:
248
Step-by-step explanation:
[tex]\frac{y}{400}: \frac{62}{100}[/tex]
y · 100 = 62 · 400
100y = 24800
100y ÷ 100 = 24800 ÷ 100
y = 248

The median of the given data is 118.
It is required to find the median.
What is median?The median is the middle value in a set of data .The median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.
here, we have,
Given:
The given date are arranged in ascending order
110 112 114 116 118 120 122 124 126 °F
Total number of the data is 9 which is odd ,
so the median is
n+1/2
Where n=number of values in data set
According to given question we have,
Median=n+1/2
Median=9+1/2
Median=5
The 5th term of the number is median of the given data i.e 118.
Therefore, the median of the given data is 118.

What is the area of the figure at the right?
Answer:
88 in
Step-by-step explanation:
find the area of each shape individually
triangles - 3x8=24 and you don't have to divide by 2 because there's 2 triangles.
rectangles - 8x4x2=64 you multiply by 2 because there are 2 rectangles.
then you add the rectangles and triangles together.
Answer:
88 (is the total area since I did not really get what you were asking)
Step-by-step explanation:
The question is basically asking to find the rectangle and triangle and then multiply both by 2.
Find the rectangle:
4 x 8 = 32
Find the triangle:
7 - 4 = 3
3 x 8/2 = 12
Multiply by 2:
32 x 2 = 64
12 x 2 = 24
Add the two up..
64 + 24 = 88

Pqr is an isosceles triangle and prs is a straight line
Answer:
∠ QRS = 132°
Step-by-step explanation:
Since the triangle is isosceles then the 2 base angles are congruent, that is
∠ PQR = ∠ PRQ = [tex]\frac{180-84}{2}[/tex] = [tex]\frac{96}{2}[/tex] = 48°
∠ PRQ and ∠ QRS are adjacent angles , so
∠ QRS = 180° - 48° = 132°
