Can you form a right triangle form 21, 220, 221

1 answer:

4 0

From Pythagorean we know x^2 + y^2 = z^2. (x and y are smaller than z).

Let’s try!

21^2 + 220^2 = 441 + 48400 = 48841.

221^2 = 48841. The same!

So the answer is yes, you can make a right angled triangle.

A sporting goods store sells triangular team pennants in two sizes. The base of one pennant is 18 in. and the length of the side

juin [17]

This is a proportion problem because the problem stated that the two team pennants are similar.

Pennant 1 = base = 18 in ; length = 9 inches
Pennant 2 = base = 6 in ; length = x ?

9/18 = x/6
9*6 = 18x
54 = 18x
54/18 = x
3 = x

The length of the side of the smaller pennant is 3 inches.

Can you answer this one please

Answer:

50⁰

Step-by-step explanation:

Since j and k are parallel lines cut by two transversals,

2+3+5=180⁰ (Allied angles)

We are given 2(60⁰) and 5(70⁰)

so,

60⁰+3+70⁰=180⁰

60+70=130

130⁰+3=180⁰

Bring the 130⁰ to the R.H.S

3=180⁰-130⁰

Therefore,

3=50⁰
