Answer:
Hint: Use the Angle Addition Theorem and the fact that a line is made up of two opposite rays. Given: m∠1 = 62° and lines t and l intersect
Explanation:
Step-by-step explanation: 
 
Given: m∠1 = 62° and lines t and l intersect 
 
Prove: m∠4 = 62° 
 
Proof: 
 
Statement Reason 
 
m∠1 = 62° Given 
 
m∠1 , m∠2 are supplementary t is a straight line hence linear pair. 
 
m∠4 , m∠2 are supplementary r is a straight line hence linear pair. 
 
Angle 2=180-62 = 118 Definition of supplementary angles 
 
Angle 4 = 180-118 =62 -do- 
 
Angle 1 = Angle 4 Equality property 
 
Hence proved
