A ladder 6.5 m long rests against a vertical wall. If the foot of the ladder is 2.5m from the foot of the wall find upto how much height does the ladder reach​

The ladder reaches a height of 6 m.

Step-by-step explanation:

Given that,

Height of the ladder, H = 6.5 m

The foot of the ladder is 2.5 m from the foot of the wall.

We need to find the height does the ladder reach. If we consider a triangle in which hypotenuse is 6.5 m, foot of the ladder is 2.5 m then we need to find the height of the ladder i.e.

The ladder reaches a height of 6 m.

find out the value of b

step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
