Answer 1

Answer:

$b_1=(2A)/(h)-b_2$

Step-by-step explanation:

Given expression is;

$A=(h(b_1+b_2))/(2)$

Solving for $b_1$

Multiplying both sides by 2

$2*A=(h(b_1+b_2))/(2)*2\n2A=h(b_1+b_2)$

Dividing both sides by h

$(2A)/(h)=(h(b_1+b_2))/(h)\n(2A)/(h)=b_1+b_2$

Subtracting $b_2$ from both sides

$(2A)/(h)-b_2=b_1+b_2-b_2\n(2A)/(h)-b_2=b_1\nb_1=(2A)/(h)-b_2$

$b_1=(2A)/(h)-b_2$

What is diagonal?

It is a line segment which joins two vertices of a shape when those vertices are not on the same edge.

How to find diagonal of a kite?

The shape of a kite is rhombus whose all sides are equal to each other. Because all the sides are equal to each other, the triangles formed by the diagonals of the rhombus are congruent and the angle made on a line is equal to 180 degrees. By dividing the line into two equal parts by bisecting we can find all angles at which the diagonals are bisecting equal to 90 degrees.

Hence the diagonals of a kite meets at a right angle.
