Answer:

162°

Step-by-step explanation:

The measure of inscribed angle ADC is half the measure of the intercepted arc AC. That arc has a measure that is the same as the central angle it subtends, angle ABC.

So, central angle ABC is twice the measure of inscribed angle ADC:

m∠ABC = 2·81° = 162°

Follow the steps to solve this equation. 3(2x + 6) – 4x = 2(5x – 2) + 6 1. Use the distributive property: 6x + 18 – 4x = 10x – 4

Answer:

$x=2$ .

Step-by-step explanation:

We have been given an equation $3(2x+6)-4x=2(5x-2)+6$ . We are supposed to solve our given equation step by step.

Step 1: Use the distributive property.

$3\cdot 2x+3\cdot 6-4x=2\cdot 5x-2\cdot 2+6$

$6x+18-4x=10x-4+6$

Step 2: Combine like terms.

$6x-4x+18=10x-4+6$

$2x+18=10x+2$

Step 3: Use subtraction property of equality:

$2x-2x+18-2=10x-2x+2-2$

$16=8x$

Step 4: Use the division property of equality:

$\frac{16}{8}=\frac{8x}{8}$

$2=x$

Therefore, the solution of our given equation is $x=2$ .
