Answer:
the answer is yes
Step-by-step explanation:
Answer:
Given: DB = 7.2 cm, AE = 1.8 cm and EC = 5.4 cm and DE || BC.
DB
AD
=
AC
AE
[by basic proportionality theorem which states that if a line is drawn parallel to one side of a triangle the other two sides in distinct points, then the other two sides are divided in the same.
7.2
AD
=
5.4
1.8
AD=
5.4
7.2×1.8
AD=
10
24
⟹AD=2.4cm
Answer:
x=13
Step-by-step explanation:
since they are vertical angles, they equal each other so set both angles to have them equal each other to find x

Add 12 on both sides

Subtract tax from both sides

Divide by 2 for both sides

The ratio 5/6 is equivalent to 275/330
5:6 ⇔ 275:330
That figure obviously doesn't go with this problem. It doesn't matter; this is triangle ABC labeled the usual way.
c = 10, B = 35°, C = 65°
We have two angles and a side. The third angle is obviously
A = 180° - 35°- 65° = 80°
The remaining sides are given by the Law of Sines,



Answer: A=80°, a=10.9, b=6.3, third choice
