a. the quotient of a number and 4.2 is less than or equal to 21.
b. the quotient of a number and 4.2 is less than 21.
c. the quotient of 4.2 and a number is less than or equal to 21.
d. the quotient of 4.2 and a number is less than 21.

Answer with explanation:

The given Inequality is

→N=Number(Dividend)

→4.2=Divisor

The statement is like this, when a number is divided by , 4.2, that is Quotient is less than or equal to 21.

Option A:→ The quotient of a number and 4.2 is less than or equal to 21.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
