A contour line<span> or isoline </span>connects points<span> on a map that are of </span>equal<span> value. Examples of contour </span>lines<span> or isolines are isobars (pressure) and isotherms (</span>temperature<span>).

A triangle is equal to 180 degrees. we know that one of the angles is 118 and the other is 30 degrees. now we have a total of 148 degrees. so that means the other angle is 32 degrees. and both triangles are identical so that means
x= 32
so what i did you get 148 is i added 118 and 30 together and then i subtracted 118 from 180 to get 32
i hope this helps
