Answer 1

Ответ:

∠ C = 180 -63-38=79

Объяснение:

сумма угло в треугольнике 180

Answer 2

Triangle KLC

Given that ∠K = 38° and ∠L = 63°, we need to determine the measure of ∠C.

To find the measure of ∠C, we can use the fact that the sum of the angles in a triangle is always 180°. Therefore, we can subtract the measures of ∠K and ∠L from 180° to find ∠C.

The calculation is as follows: ∠C = 180° - ∠K - ∠L

Substituting the given values: ∠C = 180° - 38° - 63°

Simplifying the equation: ∠C = 79°

Therefore, the measure of ∠C in triangle KLC is 79°. [[1]]

Right Triangle

Given that one acute angle of a right triangle is 84°, we need to determine the measure of the second acute angle.

In a right triangle, the sum of the measures of the two acute angles is always 90°. Therefore, we can subtract the measure of the given angle from 90° to find the measure of the second acute angle.

The calculation is as follows: Second acute angle = 90° - given angle

Substituting the given value: Second acute angle = 90° - 84°

Simplifying the equation: Second acute angle = 6°

Therefore, the measure of the second acute angle in the right triangle is 6°. [[2]]
