Triangle QTR=~ triangle SRT
Answer:
D) Image 4 (4th Image)
Step-by-step explanation:
The maths class is away from the cafeteria so the line inclines upwards. The line then stays flat indicating the time spent in the same spot at his maths class. Then he starts heading back to the cafeteria and the line inclines downward. He then stops along the way for a drink which indicates the second flat line where he spent time in the same spot. Finally, the line inclines all the way down towards the bottom showing that he is back at the cafeteria.
The value of ? and X are 12 and 24 respectively
<h3>Similarity theorem of a triangle</h3>
A triangles is 2D shape with three sides and angles.
From the given diagram, the ratio of similar sides is equal to a constant as shown;
15/20 = 9+15/20+x
Cross multiply
15/9+15 = 20/20+x
15/24 = 20/20+x
Comparing with the given ratio
? = 24
X = 20+x
Find x
15(20+x) = 480
300 + 15x = 480
15x = 180
x =12
Fro the given expression
x/32 = 9/?
12/32 = 9/?
12 ? = 32 * 9
? = 24
Hence the value of ?and x from the given diagram is 12 and 24 respectively
