Use the properties of angle measures to find the measure of each marked angle.
Find the measure of the marked angles.
a = (4x + 6)°
b = (3x + 24)°
Sorry, I don't have a picture, but the angles are directly across from each other.

From rhw description given,it appears that the angles are vertically opposite each other.
Therefore,
4x+6=3x+24
4x-3x=24-6=18
x=18
The angle,are,therefore,
4*18+6 or 78 degrees each.

It has no longer something to do with trigonometry. Its string constraints. while the rope is pulled, the two pulleys turn. the element is, the size of rope that passes the 1st pulley is comparable as that passes in the process the 2d. there is not any addition or subtraction of rope in between. So, the outer limitations of the pulleys giving out comparable lengths of rope. Distance lined via outer boundary = radius x form of radians is equivalent for the two 7 x attitude = 12 x 5 attitude = 60 / 7 = 8.57 radians Sorry, my undesirable... :P

Your description is too vague. If you have two lines intersecting (forming 4 angles):
if a and b are alternate angles, a=b
if a and b are next to each other a+b=180

so then they are vertical angles?
which would mean they are equal
so 4x+6 = 3x+24 and x = 18
so the angles are each 78degrees

vertically opposite angles are congruent
so
4x+6 = 3x +24
x=18 degrees

Directly across from each other like this...?
-------------
\ <-angle a
\
\
angle b > \
--------------------
this doesn't show up right but do you get the point? there should be a bunch of spaces to form a diagonal line
if that's so the angle are equal. set the two equations to equal each other and solve for x
