Determine whether each of the following triangles is a right-angled triangle

Mathematics
1 answer:
Fantom [35]3 years ago
4 0

Answer:

Yes

Step-by-step explanation:

To determine if this is a right triangle, use the pythagorean theorem and see if a^2 + b^2 is equal to c^2.

a^2 + b^2 = c^2

12^2 + 16^2 = 20^2

Evaluate the exponents.

144 + 256 = 400

Add them together.

400 = 400

Since a^2 and b^2 add up to equal c^2, this is a right triangle.

Can someone help me with 8÷2 2/9 −2 11/15
dsp73

Answer:

7/3 or 13/15

Step-by-step explanation:

So you told me that it will be

8/(20/9) -2 11/15 I put parenthesis to make it easier to understand for me

so you must know that a/(b/c)=ac/b si

72/20 -2 11/15 so we work with -2 11/15 which is equal to -30/15 + 11/15 and that will be -19/15 so we have

72/20 - 19/15 we simplify

18/5 - 19/15 so we multiply and divide by 3 in 18/5

54/15 - 19/15 and we add up

35/15 which is equal to

7/3

If this is wrong <u>so we work with -2 11/15 which is equal to -30/15 + 11/15 </u> well it should be so we work with -2 11/15 which is equal to -30/15 - 11/15 and  that equals -41/15 and we get

54/15-41/15

13/15
