Question

please any one can send me the correct answer of this question​

Answer 1

Answer:

As follows

Step-by-step explanation:

For no 3,

angle a = angle b (corresponding angles)

angle b = 40

angle b and c are alternate interior angles

For no 4,

BD is altitude,

Therefore angle ADB=90 since altitude=perpendicular(standing on 90 degrees)

AN is median on side BC

Median Bisects The side

SO BC=2BN=2*5=10
