Triangle xyz is equilateral with vertices located on circle w. circle w is shown. line segments w y, w z, and w x are radii. lines are drawn to connect the points on the circle to form a triangle. sides z x, x y, and z y are congruent. which measurements are correct? select two options. marc x y = 60° marc y z = 120° marc z x = 180° m∠xwz = 60° m∠ywz = 120°

step-by-step explanation:

the radii divide the circle into thirds. each (short) arc and each central angle have the measure 360°/3 = 120°.

arc yz and central angle ywz have measures of 120°.

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
