This makes sense because every point on the gold line is a solution to the equation
y
=
1
2
x
+
3
y=
2
1
​
x+3start color #e07d10, y, equals, start fraction, 1, divided by, 2, end fraction, x, plus, 3, end color #e07d10, and every point on the green line is a solution to
y
=
x
+
1
y=x+1start color #0d923f, y, equals, x, plus, 1, end color. So, the only point that's a solution to both equations is the point of intersection

Answer:

  • 48°
  • ∠Y ≅ ∠X

Step-by-step explanation:

<h3>Question 1</h3>

<u>Prove that The two triangles are congruent</u>

  • ∠ABD ≅ ∠BDC - given
  • BD ≅ DB - reflexive property
  • ∠ADB ≅ ∠CBD - given
  • ΔABD ≅ ΔCDB - ASA postulate

<u>Find the measure of angle C</u>

  • ∠A ≅ ∠C - Corresponding  parts of congruent triangles
  • m∠C = m∠A = 180° - (62° + 70°) = 180° - 132° = 48°
<h3>Question 2</h3>

<u>Given </u>

  • ΔXYZ with XZ ≅ YZ

Opposite angles are corresponding to the sides.

Therefore the angles opposite to congruent sides are also congruent:

  • ∠Y ≅ ∠X
