We can see that the two triangles share an angle and all their sides are parallel, thus by Tales theorem, they are in Tales position, which proves that they are congruent.

we can see from figure that:
call x and y the unknown segments TA and TN, then we have:

3.3/(3.3 + x) = 6/8

8*3.3 = 6(3.3 + x)
x = 1.1

and then the proportion still holds for those sides as well as AN and RI

we also have:
y/(y + 1.6) = 6/8
8y = 6y + 9.6

y = 4.8

<span>and then the proportion still holds for those sides as well as AN and RI</span>

1/5+1/7+3/21 the answer is
inessss [21]

Answer:

<h2>17/35</h2>

Step-by-step explanation:

We need to get all the fractions with a common denominator before we can solve the problem.

The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.

1/7 = 3/21

Add

\frac{3}{21} + \frac{3}{21} =\frac{6}{21}

6/21 = 30/105

1/5 = 21/105

\frac{30}{105} + \frac{21}{105} = \frac{51}{105}

Simplify

\frac{51}{105} / \frac{3}{3} =\frac{17}{35}

<h3>ANSWER: 17/35</h3>

I'm always happy to help :)
