Atriangle can have at most one right angle or acute angle ? is this true?

it can have at most one right angle but at most, 2 acute angles

Step-by-step explanation:

A triangle is a shape bounded by 3 sides and it has three angles.

The sum of the angles is 180 degrees

A right angle is 90 degrees. So a tight angled triangle has one of the angles equal to 90 degrees.

An acute angle is an angle lesser than 90 degrees.

An obtuse angle is an angle greater than 90 degrees but lesser than 180 degrees. Assuming we have a right angle triangle.

So a triangle can have at most one right angle while a triangle can have more than one acute angle. For example, a right angled triangle has two acute angles. So also, a triangle containing an obtuse angle has two acute angles

11

step-by-step explanation:

32.50-7.50=25

225/25=11

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
