Question

In triangle ABC M is the midpoint of ab and N is the midpoint of AC
1) If MN=(4x-2) and BC=(6x+3) Find x
2) If Angle MNC =(3y+10) and Angle ACB = 50 Find value of y

Answer 1

Step-by-step explanation:

by mid point theorm we get,

MN=1/2BC

4X-2=1/2(6X+3)

8X-4=6X+3

2X=7

X=7/2

X=3.5

3y+10=50

3y=40

y=40/3

y=13.34
