(3x+28)
O 14
O20
O 12
O 19

Answers

Answer:

x = 14

Step-by-step explanation:

The triangle has 2 congruent legs and is isosceles with 2 base angles being congruent , then

5x = 3x + 28 ( subtract 3x from both sides )

2x = 28 ( divide both sides by 2 )

x = 14

∠2≅∠4, m∠2=110°. Find the measures of angles 1, 3, and 4 and explain how you know.

Answers

Answer:  ∠1 =70° ;   ∠3 = 70° ;  ∠4 = 110°

Step-by-step explanation:

∠2 ≅ ∠4 = 110°                       [exterior alternate angles are equal]  

∠1 = 180° - 110° = 70°             [since angles on a line have a sum of 180°]

∠1 = ∠3 = 70°                        [since vertically opposite angles are equal]
