Answer:

The original number would have been 2/3

Step-by-step explanation:

In order to find this, we first need to turn the word problem into a numerical problem. For the purpose of this, let the number equal x.

7(x - 4/7) = x

7x - 4 = x

-4 = -6x

2/3 = x

As you know
sin = opp / hyp
cos = adj / hyp
tan = opp/adj

so
tan(Y) = opp/adj = 8/15
cos (X) = adj / hyp = 8/17
tan(X) = opp/adj = 15/8
sin(Y) = opp / hyp = 8/17
cos(Y) = adj / hyp = 15/17

so answers
tan(Y) = opp/adj = 8/15
tan(X) = opp/adj = 15/8
sin(Y) = opp / hyp = 8/17

Answer:

option B. MB/AM=NC/AN

Step-by-step explanation:

we know that

The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally

In this problem

MN is parallel to BC

MN intersect AC and divide into AN and NC

MN intersect AB and divide into AM and MB

Applying the Triangle Proportionality Theorem

$\frac{AN}{NC}=\frac{AM}{MB}$

Rewrite

$\frac{MB}{AM}=\frac{NC}{AN}$
