Calculate the area of this triangle.
17 cm
8 cm
15 cm-
Area - Triangles
Overview
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

Answer: X = -4
Step-by-step explanation:
90 - 5x + 62 -2x = 180
152 - 7x = 180
-7x = 28
x = -4
Check your answer by pluging in the vaule of x
90 - 5(-4)
90 + 20 = 110
62 - 2(-4)
62 + 8 = 70
110 + 70 = 180
Checks out.
Answer: 110 degrees and 70 degrees
Step-by-step explanation:
These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180
Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180
Subtract 152 from both sides of the equation.
-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70
We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

The side length of an equilateral triangle is 6 cm. What is the height of the triangle?
I’m super confused !!
9514 1404 393
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.

Brainiest answer to whoever is correct
Answer:
39 degrees
Step-by-step explanation:
Vertical angles are opposite angles made by two intersecting lines, this means they share a vertex. Vertical angles are always congruent. Congruent angles have the same measurements, so the other angle must be 39 degrees.

situation is graphed on the coordinate plane below, where x represents the smaller number and y represents the
larger number
Answer:
The answer is that in my case y (the smaller number) is 2 and x (the bigger number) is 6
Step-by-step explanation:
The equations are x=3*y and y+4=x. This makes y=2 and x=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.
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
On a coordinate grid, point R is at (−6, 2) and point S is at (8, 2). The distance (in units) between points R and S is ______. (Input only whole numbers, such as 2.)
Answer:
Step-by-step explanation:
Difference of x-coordinates = -6-8 = -14
Difference of y-coordinates = 2-2 = 0
Distance = √((-14)^2+0^2) = 14
