Answer:
m∠RQS = 102°
m∠SQT = 78°
General Formulas and Concepts:
Definition of a Line: A line is 180°
Order of Operations: BPEMDAS
Explanation:
Step 1: Set up equation
m∠RQS and m∠SQT must add up to m∠RQT.
m∠RQS + m∠SQT = m∠RQT
(20x + 2) + (15x + 3) = 180
Step 2: Solve for x
- Combine like terms: 35x + 5 = 180
- Subtract 5 on both sides: 35x = 175
- Divide 35 on both sides: x = 5
Step 3: Find m∠RQS
- Define: m∠RQS = 20x + 2
- Substitute: m∠RQS = 20(5) + 2
- Multiply: m∠RQS = 100 + 2
- Add: m∠RQS = 102°
Step 4: Find m∠SQT
- Define: m∠SQT = 15x + 3
- Substitute: m∠SQT = 15(5) + 3
- Multiply: m∠SQT = 75 + 3
- Add: m∠SQT = 78°
