Question

Углы DAB и DAF- смежные. Угол DAB в три раза больше угла DAF. Найдите угол DAF

Answer 1

< DАВ : < DAF=3:1. Сумма смежных углов равна 180 градусам. Значит <DAF=180/(3+1)=45. <DAB=3*45=135

Answer 2

Finding the Angle DAF

To find the angle DAF, we can use the information provided that the angle DAB is three times larger than the angle DAF.

Given: - Angle DAB is three times larger than angle DAF.

Let's denote the measure of angle DAF as x. Then, the measure of angle DAB is 3x.

We know that the sum of the measures of adjacent angles is 180 degrees.

So, we can set up the equation: x + 3x = 180 4x = 180 x = 45

The measure of angle DAF is 45 degrees.
