Answer:
a) <DXC and < CXB are complementary angles
b) Supplementary angles
<AXB and <DXB
<AXC and DXC
Step-by-step explanation:
Complementary angles: Two angles are complementary angles if their sum equals 90°
Supplementary angles: Two angles are Supplementary angles if their sum equals 180°
a) Name a pair of complementary angles
So, <DXC and < CXB are complementary angles
b) Name two Supplementary angles pair
<AXB and <DXB (their sum equals 180°)
<AXC and DXC ((their sum equals 180°))
The amount of interest he would earn in one (1) year is equal to $80.
<u>Given the following data:</u>
- Interest rate = 10% = 0.1
To determine how much interest he would earn in one (1) year:
<h3>How to calculate
simple interest</h3>
Mathematically, simple interest is given by this formula:

<u>Where:</u>
- S.I is the simple interest.
- P is the principal or starting amount.
- T is the time measured in years.
Substituting the given parameters into the formula, we have;

Simple interest = $80
