Compute 1 + 2 + 3 +....+ 1,997 + 1,998 + 1,999
sp2606 [1]

Answer:

1 999 000

Step-by-step explanation:

Formula:

1+2+3+.\ .\ .+n=\frac{n\times \left( n+1\right)  }{2}

………………………………………

Then

1+2+3+....+1997+1998+1999=\frac{1999\times \left( 1999+1\right)  }{2}

1+2+3+....+1997+1998+1999=\frac{1999\times \left( 2000\right)  }{2}

1+2+3+....+1997+1998+1999=\frac{3998000  }{2}

1+2+3+....+1997+1998+1999=1999000

Which side in the smallest triangle would correspond with HI in the largest triangle?
tensa zangetsu [6.8K]

The side of the small triangle that will correspond to the side of HI is side IK.

<h3>How to find corresponding side of similar triangles?</h3>

Similar triangles are triangles that have the same shape but different size.

In similar triangles, corresponding sides are always in the same ratio.

The corresponding angles are equal.

Therefore, the side of the small triangle that will correspond to the side of HI is side IK.

BRAINLY!!!- if a=7, b=8, and c=9.2 is this a right triangle? why?
Travka [436]

Answer:

no

Step-by-step explanation:

If this were a right triangle we would assume the Pythagorean Theorem to prove it

a^{2} +b^{2} =c^{2}

7^{2} +8^{2} =9.2^{2}

this gives us

49+64=84.64

this is 143=84.64 and therefore not equal and not a right triangle

The triangles below are similar.
andre [41]

Answer:

AAA (angle-angle-angle) similarity theorem

Step-by-step explanation:

The two given triangles PSR and XYZ, are similar.

And all their angles are also similar.

We can conclude, that both are similar based on AAA similarity theorem.

The AAA (angle-angle-angle) similarity theorem states that two triangles have their corresponding angles equal, if and only if their corresponding sides are proportional.

XZ is proportional to SR. XY is proportional to SP and YZ is proportional to PR.
