In a triangle ABC two points D,E are taken on BC so that angle BAD=angle DAE=angleCAE. Determine AE if AB=5,BC=10 angle BAC=90.
lord [1]

Answer:

AE = 7.5

Step-by-step explanation:

Since <BAC = 90^{0}, then;

<BAD = <DAE = <CAE = 30^{0} (complementary angles)

From ΔABC, applying the Pythagoras theorem to determine the length of side AC;

/BC/^{2} = /AC/^{2} + /AB/^{2}

/10/^{2} = /AC/^{2} + /5/^{2}

100 = /AC/^{2} + 25

/AC/^{2} = 100 - 25

/AC/^{2} = 75

AC = \sqrt{75}

Applying trigonometric function to ΔCAE,

Cos 30^{0} = \frac{AE}{\sqrt{75} }

AE = \sqrt{75} × Cos 30^{0}

    = 7.5

Therefore, AE = 7.5

Can someone help me understand this?
choli [55]

Get the equation to slope-intercept form: y = mx + b

6x + 3y = 6

Subtract 6x from both sides. This will give you 3y = -6x + 6.

Then, divide by 3 on both sides. This gives you y = -6x + 2.

2 is your y intercept and -6 is your slope.
