Yes, because they are similar(or you can call congruent), proved by SAS or simply HL.

For that to happen, they must be similar. Maybe you've heard of Thales theorem?

So, let's see how the ratio of vertical to horizontal is:

3/7 (in the first triangle)
9/21 (in the second triangle)

Is 3/7=9/21? Yup. So that it is the second one.

Find the sum of an infinite geometric series where a1 = 180, and the common ratio is r = 3∕4 ? Question 9 options: A) 240 B) 360

Len [333]

Answer:

The sum of this geometric series is 720.

Step-by-step explanation:

The sum of a infinite geometric series is given by the following formula:

$s = \frac{a_1}{1 - r}\\$

Applying the data from the problem, we have:

$s = \frac{180}{1 - \frac{3}{4}}\\\\s = \frac{180}{\frac{4 - 3}{4}}\\\\s = \frac{180}{\frac{1}{4}}\\\\s = 180*4 = 720$

The sum of this geometric series is 720.

I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.
