Using a = 15, b =12 and
c = 21, is triangle ABC
a right angle triangle?
Yes
No
Answer:
[tex]15^{2}+12^{2}=21^{2}\\225+144=441\\369=441[/tex]
left side is not equal to the right. It means that is not right triangle
Step-by-step explanation:
No, triangle ABC is a right angle triangle.
What is triangle ?Triangle is a two dimensional shape having three side and sum of all angles is equals to [tex]180^0[/tex].
We have,
[tex]a=15[/tex], [tex]b=12[/tex] and [tex]c=21[/tex]
So,
To be a right angle triangle it must satisfy the Pythagoras triangle.
i.e.
[tex]H^2=P^2+B^2[/tex]
So,
[tex]21^2=15^2+12^2[/tex]
[tex]441=225+144[/tex]
[tex]441\neq 369[/tex]
So, triangle ABC is not a right angle triangle as it does not satisfy the Pythagoras triangle.
Hence, we can say that No, triangle ABC is a right angle triangle.

A, B & C lie on a straight line. D, C & E lie on a different straight line.Angle y = 115° and angle z = 62°.Work out x, explaining each stage of your working in the comment box.
Answer:
x = 127°
Step-by-step explanation:
Find the diagram attached
First we need to get <DBC
<DBC =180-y
<DBC = 180-115
<DBC = 65°
The sum of interior angles is equal to exterior
Hence <DBC+ z = x
65+62 = x
x = 127°

Two line painting trucks are painting lines on the side of a roadway. One truck painted 24 miles in 3 hours. The other truck painted 20 miles in 4 hours. Which ratio
Answer:
[tex]A : B = 8 : 5[/tex]
Step-by-step explanation:
Given
Truck A
[tex]Distance = 24 miles[/tex]
[tex]Time = 3 hours[/tex]
Truck B
[tex]Distance = 20 miles[/tex]
[tex]Time = 4 hours[/tex]
Required
Determine the ratio of their speeds
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
For A:
[tex]A= \frac{24}{3}[/tex]
[tex]A = 8[/tex]
For B:
[tex]B = \frac{20}{4}[/tex]
[tex]B = 5[/tex]
So, the ratio is:
[tex]Ratio = A : B[/tex]
[tex]A : B = 8 : 5[/tex]

If 5 boys can eat 16 slices of pizza, then how many slices can 20 boys eat?
Can you help me explain
Answer:
x = 10
Step-by-step explanation:
We need to isolate X.
3x - 7 = x + 13
subtract 13
3x - 7 - 13 = x
combine like terms
3x - 20 = x
subtract 3x
- 20 = x - 3x
Combine like terms
- 20 = - 2x
Divide by -2
10 = x

Answer:
180=144+3X
X=12
Step-by-step explanation:
angles must add to 180
180=45+80+3X+19
gather like terms
180=144+3X
subtract
36=3X
divide
X=12
Answer:
X = 12
All triangles add up to 180* so we first need to add the angles
45 + 80 = 125
180 - 125 = 55
We need to have x contribute to the angle being 55*
3 + 19 = 22
55 - 22 = 33
3 x 12 + 19 = 55
x = 12
