To find: the length of base and the lengths of congruent sides.
Explanation of Solution
Given information:
Let the base of an isosceles triangle be “
Calculation:
The triangle representing the given condition is shown below.
Now evaluate the base by using tangent function as follows:
Thus the length of base is 29.9 cm.
The length of congruent sides can be evaluated by using sine function as follows:
Thus the length of congruent sides is 15.8 cm.
