## What is the angles of a triangle which are in the ratio 3/4 5?

=45o. The angles of a triangle are in the ratio 3:4:5.

**What is the smallest angle in a 3 4 5 triangle?**

45 is the smallest angle in your triangle.

**Is the measure of angles of a triangle are in the ratio of 3 ratio 4 ratio 5 What is the measure of the smallest angle of the triangle?**

Given : The measures of angles of a triangle are in the ratio of 3 : 4 : 5. We know that, the sum of three angles of a triangle is 180°. Hence, the measure of the smallest angle of the triangle is 45°.

### Is it possible to have a triangle with sides 4cm 5cm and 9cm?

No because the sum of the two shorter sides must exceed the third side. Physically, this is a pathological case. This means that the 4 cm and 5 cm legs would lie flat against the 9 cm leg. So, this is not a triangle.

**What is a right triangle ratio?**

45°–45°–90° triangle The sides in this triangle are in the ratio 1 : 1 : √2, which follows immediately from the Pythagorean theorem. Of all right triangles, the 45°–45°–90° degree triangle has the smallest ratio of the hypotenuse to the sum of the legs, namely √22.

**What are the measures in triangle used for writing calculating the ratio?**

3 Answers By Expert Tutors. Since the ratio of the angles is 7:2:1, we can write the angles as 7x, 2x, and x, for some x. Since the sum of the angles in a triangles is 180, we have 7x + 2x + x = 180. Combining the x’s on the left-hand side, we have 10x = 180.

## What is the meaning of s in Heron’s formula?

semi-perimeter

The s in Heron’s formula denotes the semi-perimeter of a triangle, whose area has to be evaluated. Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.

**What is ratio in triangle?**

The ratio of the opposite to the adjacent for any right triangle is defined to be the tangent (tan) of the angle. For the red triangle the value of the tangent is: tan(c) = 1 / 2 = .5. For the blue triangle, we keep the angle c the same, but we have doubled the size of the opposite side and the adjacent side.

**What is the ratio of a triangle?**

If a triangle is a 30-60-90 right triangle, the ratio of the sides (short leg:long leg:hypotenuse) is 1:√3:2.
