Answer:

∠A=123°.

Step-by-step explanation:

From the given figure it is clear the CD and CE are two tangent lines on circle with center A.

Radius is perpendicular to the tangent at the point of tangency.

\angle ADC=90^{\circ}

\angle AEC=90^{\circ}

Smaller arc DE = (5x-2)°

It means central angle DAE is (5x-2)°.

\angle DAE=(5x-2)^{\circ}

Now, ADCE is a quadrilateral and sum of all angles of a quadrilateral is 360 degrees.

\angle ADC+\angle DCE+\angle AEC+\angle DAE=360^{\circ}

90^{\circ}+(2x+7)^{\circ}+90^{\circ}+(5x-2)^{\circ}=360^{\circ}

(7x+5)^{\circ}+180^{\circ}=360^{\circ}

(7x+5)^{\circ}=360^{\circ}-180^{\circ}

(7x+5)^{\circ}=180^{\circ}

7x+5=180

7x=175

x=25

The value of x is 25.

\angle A=5x-2=5(25)-2=125-2=123^{\circ}

Therefore, the measure of ∠A is 123°.

40+6X = -7(4x+4)<br> Enter you answer
tester [92]

Answer:

x = -2

Step-by-step explanation:

40+6X = -7(4x+4)

Distribute

40 +6x = -28x -28

Add 28x to each side

40 + 6x +28x = -28x-28 +28x

40 + 34x = 28

Subtract 40 from each side

40 + 34x -40 = -28-40

34x = -68

Divide each side by 34

34x/34 = -68/34

x = -2
