Lines and Angle...

In figure, if $$AB\parallel CD$$, then find the value of $$\angle PRG$$

In figure if $$BA\parallel DF, AD\parallel FG, \angle BAC=65^o$$ and $$\angle ACB=55^o$$, then find $$\angle FGH$$.

The measure of an angle is three times the measure of its complement. The angles are:

$$AB\, ||\, CD\, ||\, EF$$ and $$GH\, ||\, DI$$. If $$\angle DIH\, =\, 95^{\circ}$$ then the measure of $$\angle GCD$$ is equal to

In figure, if $$AB\parallel CD$$, then find the value of $$\angle CHF$$

In figure, if $$AB\parallel CD$$, then find the value of $$x$$

Lines $$m$$ and $$n$$ are cut by a transversal so that $$\angle 1$$ and $$\angle 5$$ are corresponding angles. If $$\angle 1=26x-{7}^{\circ}$$ and $$\angle 5=20x+{17}^{\circ}.$$ What value of $$x$$ makes the lines $$m$$ and $$n$$ parallel?

If ray $$PQ$$ and $$RS$$ are parallel as given in the figure, then fine $$a+b+c$$.

In the given figure, $$AB\parallel  CD$$. Find $$x$$.

Three lines intersect at a point generating six angles. If one of these angles is $${90}^{o}$$, then the number of other distinct angles is:
