Answer:

946

Step-by-step explanation:

we know that

The formula to find the sum is equal to

S=(a1+an)n/2

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

n=11

a1=(98-2(1))=96

an=(98-2(11))=76

substitute the values in the formula

S=(96+76)(11/2)=946

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing side length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 72

Leg <em>b</em> = 65

Hypotenuse <em>c</em> = <em>x</em>

<em />

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    72² + 65² = x²
  2. Exponents:                           5184 + 4225 = x²
  3. Add:                                      9409 = x²
  4. Isolate <em>x</em>:                               97 = x
  5. Rewrite:                                x = 97
