Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h

23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified


24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values

.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.

In any circle of radius R, how many arcs with lengths R fit into the circumference?
xenn [34]

<h2>~<u>Solution</u> :-</h2>

If we take the radius of a circle be <u>R</u>. Then, we can define that,

$ R = x $

Hence,

Arcs will be as $ 4x $. As,

A circle can be divided into four parts according to the radius.

Hence, we know that,

x \times 4

\mapsto \: 4x

  • Hence, <em>according to the radius R</em>, a circle can have <u>4 arcs</u>.
