Lines AB and CD and are parallel. Find the measures of the three angles in triangle ABF.
Airida [17]

Answer:    ∠B = 42°   ∠A = 23°  ∠F = 115°

Step-by-step explanation:

∠B≅∠C  alternate interior angles  42°

  ∠CDF is supplementary to ∠CDE,

so m∠CDF = 23°  and ∠FAB≅∠CDF so m∠FAB= 23°

<em>also ∠A ≅ CDE  corresponding angles  157° ∠FAB is suplementary to ∠A </em>

<em>so 180 - 157 = 23 gives the m∠FAB</em>

The sum of the angles of a triangle is 180°, so m∠AFB = 180 -(23 +42)

180- 65 = 115 = m∠F

Answer: 31.5

Concept:

When encounter questions that ask for operation on algebraic expressions, using BODMAS or PEMDAS method would be easier. Since this question asked for using BODMAS, then it is:

  • Bracket
  • Order
  • Division
  • Multiplication
  • Addition
  • Subtraction

Solve:

<u>Given</u>

2 × 3 + 45 ÷ 2 - 6 + 9

<u>Simplify by division</u>

=2 × 3 + 22.5 - 6 + 9

<u>Simplify by multiplication</u>

=6 + 22.5 - 6 + 9

<u>Simplify by addition</u>

=28.5 + 9 - 6

=37.5 - 6

<u>Simplify by subtraction</u>

=31.5

Hope this helps!! :)
