Answer:

40cm

Step-by-step explanation:

1. To find the missing leg, use the Pythagorean theorem a²+ b² = c² and substitute the numbers a² + 8² = 17².

2. So a = 15 since 17²-8² = 289 - 64 =225 and the square root of 225 is 15

3. Now that all the lengths have been found. So the perimeter of the right triangle is 40cm.

What is the summation notation for the geometric series 1/2+2+8+32+128?
Karolina [17]

The summation notation is ∑ (4^{n} -1)\\/2.

<h3>What is geometric progression?</h3>

The common ratio multiplied here to each term to get the next term is a non-zero number.

Given:  1/2+2+8+32+128

Using,

a_n= a_1r^{n-1}

We have,

a1 =1/2 and r= 4

notation is : An= ∑ (4^{n} -1)\\/2

Hence, the notation is  An= ∑ (4^{n} -1)\\/2.
