Answer:
Step-by-step explanation:
Given
The attached triangle
Such that K is parallel to L
Required
Find the value of a and b
From the properties of parallel triangles;
Provided that k is parallel to l, then
Multiply both sides by (60)(40)
Open Bracket
Subtract 40a from both sides
Divide both sides by 20
Similarly;
Multiply both sides by (60)(40)
Open Bracket
Subtract 40b from both sides
Divide both sides by 20
