Answer:
c. 52
Step-by-step explanation:
since that triangle QRE is a right angle triangle
therefore QE = root 5²_3² = 4 cm " pythagorean "
since triangle PQE is a right angle triangle
therefore PQ= root 4²+6²= 2 root 13 = root 52
The length of side PQ in the figure given in the task content is; 6.48.
We are required to determine the length of side PQ;
It follows from Pythagoras theorem that;
5² - 3² = (PQ)² - 6²
(PQ)² = 16 + 36
PQ = √42.
PQ = 6.48
