answer:
x = 4[tex]\sqrt{2}[/tex] or 5.6568
step-by-step explanation:
know the formula and plug informula: a^2 + b^2 = c^2
now plug in what we havewhatever the RIGHT ANGLE points to is the HYPOTENUSE or cthe other two sides are the "legs" or a and ba^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4[tex]\sqrt{2}[/tex]
in this case, b would be used as xx = 4[tex]\sqrt{2}[/tex] or 5.6568 (exact value)

Is the ratio 15 : 12 equivalent to 5 : 3 and 10 : 6? Explain.
Answers
Answer:
Yes it is
Step-by-step explanation:
When we simplify 15:12, we receive 5:3
Therefore, 5:3 is equvilaent to 15:12
Using this unit ratio, we can solve for other rations
For example, 5:3, the unit ratio, times 2 is 10:6
5 * 2 = 10
3*2 = 6
10, 6 = 10:6

Anyone know this?? Question: find the area of the shape. Don’t forget your units and use 3.14 if you need to use pi.
Answers
Area of this shape = 614²
Answer with steps :Length of side of the first square = 10
It's area :
[tex] =\tt side \times side[/tex]
[tex] = \tt10 \times 10[/tex]
[tex] = \tt {100}^{2} [/tex]
Thus, the area of the first square = 100²
Length of the side of the second square = 10
It's area :
[tex] = \tt \: side\times side[/tex]
[tex] =\tt 10 \times 10[/tex]
[tex] = \tt{100}^{2} [/tex]
Thus, the area of the second square = 100²
Length of the side of the third square = 10
It's area :
[tex] =\tt side \times side[/tex]
[tex] = \tt 10 \times 10[/tex]
[tex] = \tt {100}^{2} [/tex]
Thus, the area of the third square = 100²
(pi value = 3.14)
Radius of the first semicircle = 10 cm
It's area :
[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]
[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]
[tex] = \tt\frac{3.14 \times 100}{2} [/tex]
[tex] =\tt \frac{314}{2} [/tex]
[tex] =\tt {157}^{2} [/tex]
Thus, the area of the first semicircle = 157²
Area of the second semi circle :
= area of the first semicircle
= 157²
Thus, the area of the second semicircle = 157²
Total area of the figure :
= Area of the 3 squares + Area of the two semi circles
[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]
[tex] = \tt300 + 314[/tex]
[tex] = \tt {614}^{2} [/tex]
Therefore, the total area of the figure = 614²
Two of the angles in a triangle measure 21° and 40°. What is the measure of the third angle
Answers
Answer: 119°
Step-by-step explanation:
The total of the interior angles of a triangle is 180° so if you add the two angles you have, you get 61 and just subtract that from 180 to get the missing angle.

The side length of an equilateral triangle is 6 cm. What is the height of the triangle?

Answers

Answer:
(c) 3√3
Step-by-step explanation:
The altitude forms the long side of a 30°-60°-90° right triangle whose short side is 6/2 = 3 cm.
The ratios of side lengths in a 30°-60°-90° triangle are ...
1 : √3 : 2
Multiplying these ratio values by 3 gives the right triangle side lengths of ...
3 : 3√3 : 6
where 6 is the side length of the equilateral triangle. The length 3√3 is the altitude of that equilateral triangle.
The height of the triangle is 3√3 cm.
Calculate the area of this triangle.
17 cm
8 cm

Area - Triangles
Overview
Answers
Answer:
There are 3 possible answers because you didn't state which value was base or height.
Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*8)
A = 1/2(120)
A = 60
Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)
A = 1/2(b*h)
A = 1/2(17*8)
A = 1/2(136)
A = 68
Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*17)
A = 1/2(255)
A = 127.5

m∠RST=m∠RSV+m∠VST
m∠RSV=m∠VST
hence
m∠RST=2*m∠RSV --------> equation 1
we have
m∠RST=(6x-24)
m∠RSV=(2x+8)
Substitute in the equation 1
6x-24=2*(2x+8)
6x-24=4x+16
6x-4x=16+24
2x=40
x=40/2
x=20 degrees
therefore
the value of x is 20 degrees

over the past ten years, the towns population doubled in size. the population is currently 12,000. what was the population ten years ago?
which of the following represents the given word problem if “P” represents the population ten years ago?
1. P=2(12,000)
2. 2P=12,000
3. 2(P+10)=12,000
Answers
Answer:
If P represents the population ten years ago, the current population can be expressed as: 2P = 12,000 (or: 2 x 6,000 = 12,000). Over the past ten years, the town's population doubled in size. The population is currently 12,000. Therefore the population ten years ago was 12,000 divided by 2 = 6000.
