angle x is a supplement of angle y and angle y = 9 degree. find angle x.

Definition - When two straight lines meet at a point they form an angle. The point at which the arms meet (O) is known as the vertex of the angle. The amount of turning from one arm (OA) to other (OB) is called the measure of the angle ( AOB) and written as m AOB. An h..

When two straight lines meet at a common point, they form an angle. and are called arms of the angle BAC. The point 'A' is called the vertex. The angle formed by the two rays AB and AC is denoted by the symbol BAC. If there is only one angle at A, the..

To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. In the figure, AB = 100 cm, find (i) x and (ii)..

Identify the complementary angles. => ∠ X and ∠ Y or ∠ X and ∠ Z or ∠ Y and ∠ Z or None of the above..

Find the measures of the angles of the parallelogram. => x = 100°, y = 100°, z = 100° or x = 100°, y = 80°, z = 100° or x = 80°, y = 80°, z = 80° or x = 80°, y..

Draw a triangle ABC. Draw its angle bisectors. The angle bisectors pass through a point. Recall the procedure to draw angle bisectors: With B as centre and with a convenient radius draw an arc of a circle to cut AB and AC at X and Y. With ..

The difference between an angle and its complement is 36°. What is the supplement of the angle? => 117° or 72° or 27° or 153°..

What is the measure of an angle, if its measure is 40 less than its supplement? => 65 or 70 or 25 or 110..

Angle - When two straight lines meet at a common point, they form an angle. and are called arms of the angle BAC. The point 'A' is called the vertex. The angle formed by the two rays AB and AC is denoted by the symbol BAC. If there is only one angle..

(a) Write 0, 1, 2, 3, 4 over each column as shown above. (b) Divide each number by 4 and take the square root. The values obtained are sine ratios. (c) Write these ratios in reverse order and you obtain the cosine ratios (sin A = cos B if A + B = 90 o ) (d) Divide each sine ratio by cosine ratio a..
