Answer 2

Calculation of Side AV

To find the length of side AV, we need to convert the given measurements to a consistent unit. The length of side AV is given as 2 cm 5 mm. Let's convert this to millimeters for easier calculation.

1 cm = 10 mm

So, 2 cm = 2 * 10 mm = 20 mm

Therefore, the length of side AV is 20 mm + 5 mm = 25 mm.

Calculation of Angles SAV and SVA

The angles SAV and SVA are given as 100° and 20°, respectively.

Mathematical Relationship between Angles and Sides in a Triangle

In a triangle, the sum of all angles is always 180°. This property is known as the angle sum property of a triangle.

Therefore, we can use this property to find the measure of angle A.

Angle A = 180° - (angle SAV + angle SVA)

Substituting the given values:

Angle A = 180° - (100° + 20°) = 180° - 120° = 60°

Summary

Based on the given information, we have calculated the following:

- Side AV = 25 mm - Angle SAV = 100° - Angle SVA = 20° - Angle A = 60°
