Find the value of t in the diagram above
Attached Figure / Diagram
A
5.6cm
B
6.5cm
C
6.6cm
D
6.8cm
E
7.0cm
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
\(\frac{\text{t}}{t + 4}\) = \(\frac{7}{7 + 5}\)
\(\frac{\text{t}}{t + 4}\) = \(\frac{7}{12}\)
12t = 7t + 28
12t - 7t = 28
5t = 28
t = \(\frac{28}{5}\) = 5.6cm
