Trigonometry Question, check pic.

Lynna [10]

$\text{AD is a bisector of angle BAC, so}\\\\\angle DAC = \angle BAD = 17^{\circ}~ \text{and}~ \angle BAC = 17^{\circ} + 17^{\circ}=34^{\circ}\\\\\text{In}~ \triangle ADB\\\\~~~~~~~\tan \angle BAD = \dfrac{DB}{AB}\\\\\implies DB = AB\tan \angle BAD \\\\~~~~~~~~~~~~=21 \tan 17^{\circ}\\\\$

$\text{In}~ \triangle ABC\\\\~~~~~~~\tan \angle BAC = \dfrac{CB}{AB}\\\\\implies BC = AB \tan \angle BAC\\\\\implies DB+CD = AB\tan \angle BAC\\\\\implies CD = AB \tan \angle BAC - DB\\\\\implies CD=21\tan 34^{\circ}-21 \tan 17^{\circ}\\\\\implies x\approx8 ~ \text{cm}$

Which two numbers on the number line has an absolute value of 3?

luda_lava [24]

Solution

To find Which two numbers on the number line has an

absolute value of 3

Absolute value means " how far a number is from

zero " .

"3" is 3 away from zero .

and " -3 " is also 3 away from zero .

i.e

| 0 - 3 | = 3

| 3 - 0 | = 3

So , the absolute value of "3 " is 3

similarly , absolute value of "3 " is 3 .

Hence , the two numbers are -3 and 3
