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>
∡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>
Answer:
B.
Step-by-step explanation:
The given quadratic trinomial is;
Comparing this to , we have a=5,b=17,c=6.
Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;
We factor by grouping;
Factor further
The correct answer is B.
