Quadrilaterals ...

Find $$\angle ABC$$.

Given, in quadrilateral $$ABCD$$, $$\angle C = 64^{\circ}, \angle D = \angle C - 8^{\circ}, \angle A = 5(a + 2)^{\circ}$$ and $$\angle B = 2(2a+7)^{\circ}$$. Calculate $$\angle A$$.

Sum of all angles of a square is

The angles of a quadrilateral are in the ratio 3 : 2 : 4 : 1. Find the angles. Assign a special name to the quadrilateral.

The angles $$P, Q, R$$ and $$S$$ of $$ PQRS$$ are in the ratio $$1:3:7:9$$, find the measure of each angle.

The angles of a quadrilaterals are in the ratio $$3 : 5 : 9 : 13$$. All the angles of the quadrilaterals are:

In the figure, $$LM = LN,\  \angle PLN = 110^{\circ}$$. Then,the measure of $$\angle MLN$$ in degrees is____.

In the above figure, $$ABCD$$ is a parallelogram, $$AL \bot CD$$ and $$AM \bot BC$$. If $$AB = 12\space cm, AD = 8\space cm$$ and $$AL = 6\space cm$$, then $$AM = $$

Three angles of a quadrilateral are respectively equal to $$110^o$$, $$50^o$$ and $$40^o$$. Find the fourth angle.

Use the information given in figure to choose the correct value of $$x$$.
