The correct answer is: Option (D) x = 72°
Explanation:
When two lines are crossed by another line, the angles in matching corners are called <em>corresponding angles</em>. When the two lines are <em>parallel</em>, the corresponding angles are <em>equal</em>.
Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, <em>the corresponding angles will be the same</em>.
Since the first corresponding angle is 72°, the second angle <em>x </em>will be 72° as well. The correct answer is: x = 72° Option (D).
Answer:B.
Step-by-step explanation: I took the same class
Answer:
144-36=108
Square root 108 = 10.4cm (cb)
Soh Cah toa
Sin(55) =o/h
=10.4/h
xh
H x sin55 =10.4
÷sin55
H= 10.4/sin55
H=12.7cm
CD is 12.7cm to 3 s.f.
