Q. ∠1 and ∠2 are complementary angles. If m∠1=(x−26)∘ and m∠2=(x−28)∘, 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 definition of complementary angles.m/1+m/2=90 degreesSubstitute m/1 with (x−26) degrees and m/2 with (x−28) degrees.(x−26)+(x−28)=90
Combine and Solve: Combine like terms and solve for x.2x−26−28=902x−54=90
Isolate x: Add 54 to both sides of the equation to isolate the term with x.2x−54+54=90+542x=144
Divide and Solve for x: Divide both sides by 2 to solve for x.22x=2144x=72
Substitute and Find Measure: Now that we have the value of x, substitute it back into the expression for m/2 to find the measure of the second angle.m/2=(x−28) degreesm/2=(72−28) degreesm/2=44 degrees
