Answer:
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>
Opposite angles are corresponding to the sides.
Therefore the angles opposite to congruent sides are also congruent:
-2x-4y = 2
-2x-4y+4y = 2+4y
-2x=4y+2
Divided by 2:
-2x/-2 = 4y +2/ -2
Answer: x=-2y-1
3x +4y =8
3x + 4y = -4y = 8+-4y
3x= -4y +8
Divided by 3
3x/3 = -4y + 8/3
x=-4/3y + 8/3
