Part 1) we have
using a calculator
Part 2)
we know that
If two angles are complementary
------> complementary angles
then
In this problem
we have
The angle complementary to x is equal to
so
therefore
The following information will help us with this problem:
When we use that information in the context of this problem, we can find:
Thus, a = 15, b = 7, and c = 4.
