5)m<4=13°[being vertically opposite angle)

6)m<2+<3=180°(Being straight angle)

or,m<2=180°-110°

m<2=70°

7)m<1+m<4=180°[being straight angle]

or,m<1=180°-65°

m<1= 115°

12.5

Step-by-step explanation:

We can use ratios to solve

4        4+6

=

5         AC

4        10

=

5         AC

Using cross products

4 * AC = 5*10

4AC = 50

Divide by 4

AC = 50/4

AC =12.5
