exterior angles add up to 360 so'

9x+1+5x+12+10x-37

24x-24=360

24x=384

x=16

10(16)-37

Triangle A B C is cut by line segment S T. Line segment S T goes from side A B to side C B. Lines S T and A C are parallel. The

maksim [4K]

Answer:

Option C.

Step-by-step explanation:

Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.

Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.

Using triangle proportionality theorem we get

$\dfrac{SA}{SB}=\dfrac{CT}{BT}$

$\dfrac{SA}{10}=\dfrac{2.7}{9}$

On cross multiplication we get

$9\times SA=2.7\times 10$

$9SA=27$

Divide both sides by 9.

$SA=3$

The length of SA is 3ft.

Therefore, the correct option is C.

Serhud [2]

Remember that the period of a sinusoidal function <span>is the vertical distance between the t-axis and one of the extreme points.</span> From the graph we can infer that the period of the function is 4.5.

Also, the amplitude is<span> the distance between two consecutive maximum or two consecutive minimum points. From the graph we can infer that the amplitude of the function is 0.05 seconds.

We can conclude that the correct answer is: 0.05 seconds; 4.5
