Q. ∠1 and ∠2 are complementary angles. If m∠1=(4x+2)∘ and m∠2=(6x−12)∘, then find the measure of ∠2.Answer:
Identify Relationship: Identify the relationship between complementary angles. Complementary angles add up to 90∘.
Set Up Equation: Set up the equation using the relationship between complementary angles.(4x+2)∘+(6x−12)∘=90∘
Combine Like Terms: Combine like terms to simplify the equation.4x+6x+2−12=9010x−10=90
Add 10: Add 10 to both sides of the equation to isolate the term with the variable.10x−10+10=90+1010x=100
Divide by 10: Divide both sides of the equation by 10 to solve for x.1010x=10100x=10
Substitute for x: Substitute the value of x back into the expression for the measure of the second angle, m/_2.m/_2=(6x−12)∘m/_2=(6(10)−12)∘m/_2=(60−12)∘m/_2=48∘
