How many triangles can be made if one angle of a triangle is 95 degrees and another angle is obtuse?

That would be zero.

Obtuse means more than 90 degrees. A triangle's angles add up to 180 degrees so can't have two obtuse angles.

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'.
