Answer:

True

Step-by-step explanation:

The base angles of an isosceles triangle are equal.

The sum of the 3 angles in a triangle = 180°, thus

vertex angle = 180° - (55 + 55)° = 180° - 110° = 70°

Consider angle XZY in the attached figure. It is always 1/2 the measure of arc XY, no matter where Z may be located on the major arc XZY. This is true even when ZY is very short.

Now, consider what happens when Z falls on top of tangent point Y. The angle is still half the measure of arc XY, still 62°.

Selection C is appropriate.

_____
I apologize for any confusion caused by my choice of Z as the name of the point I added. Nothing in my explanation is intended to refer to the Z already shown in the unmodified figure.

Y=2x+6, 3y=x-2 solve for unknown variables
11Alexandr11 [23.1K]

Step: Solvey=2x+6for y:

y=2x+6

Step: Substitute2x+6foryin3y=x−2:

3y=x−2

3(2x+6)=x−2

6x+18=x−2(Simplify both sides of the equation)

6x+18+−x=x−2+−x(Add -x to both sides)

5x+18=−2

5x+18+−18=−2+−18(Add -18 to both sides)

5x=−20

5x/5=−20/5

(Divide both sides by 5)

x=−4

Step: Substitute−4forxiny=2x+6:

y=2x+6

y=(2)(−4)+6

y=−2(Simplify both sides of the equation)

Answer:

x=−4 and y=−2
