Answer: 264
Step-by-step explanation: 132 x 6 = 792
792 divided by 3 = 264
Hope this helps
If BD=DC that means triangle CDB is isosceles triangle and the measure of angles ∡CDB and ∡BCD is the same
∡CDB=∡BCD=70°The angles ∡ADB and ∡CDB are adjacent and suplementary angles
It means
∡ADB + ∡CDB = 180°
∡ADB = 180° - ∡CDB
∡ADB = 180° - 70°
<u>∡ADB = 110°</u>
Y = -(-2)^2 + 4(-2) + 1
y = -4 - 8 + 1
y = -11
A triangle with an angle >90 is an obtuse triangle the other two remaining angles would be acute <90
total degrees must = 180
