As m and n add upto 110 degrees, the third angle in the triangle must be 70 degrees.
We can see the the angle just above this is a vertical angle, so it must also be 70 degrees. So now we know the two angles next to angles O and P (let's call them O' and P') add upto 110 degrees. Also note that all angles making up a straight line must add upto 180 degrees. So, O + O' and P + P' must each add upto 180 degreesall four add upto 360 degrees. Know this and know that O' + P' add upto 110 yields O + P = 250 degrees.
Choice C

let r be the point of intersection of two lines. since, m+n= 110 therefore r= 180110 r=70 Therefore degree of opposite angle= 70 In triangle ORP, angle POR = 180o angle OPR = 180p angle ORP = 70
180o+180p+70=180 op=250 o+p=250
Ans = C
PS : I have used O and P as vertices of triangle just for the sake of explanation.

In the figure below, a=b a=180(m+n) = 180110 = 70 therefore b= 70 O = b+ 180P O+P= b+180 = 70+180 = 250 answer: C

Answer = C) 250 As vertically opposite angles are same,\(\angle{ACB} = 70^{\circ}\) Attachment:

Sum of remaining angles would also be the same 180o + 180p = 110 o+p = 360110 = 250

Well, since the opposites of O and P add up to 110, and these four angles together must measure up to 180+180=360, you just substract 110 from 360 to get 250. Ans c
