25. The sides of a parallelogram have lergtho of 18 anA 26 t and one angle f 29. Find the long th of the longer diagonal.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Consider a paralog ram ABCD. Let AB=26 cm. and AD=18 cm. and angle A is 39 degrees.
For a polarogram, opposite sides are parallels and equal in length. The diagonals drawn by cutting the two opposite acute angles will be the largest diagonal for a polarogram.
Thus, in figure the diagonal AC is greater than the diagonal BD, since diagonal AC is drawn by connecting the acute angles.
Extend the side AD and mark point E in such a way that EC is perpendicular to AE.
Consider the right angle triangle CBE.
The length of the side BE is,
The angle EBC and angle B will be equal because they are the corresponding angles formed by cutting a pair of parallel lines.
The expression to calculate the length of side CE is,
Substitute values in the above expression.
