Answer:

D) 72°

Step-by-step explanation:

Sum of angles 7 and 8 is 180° as they are supplementary

Angles 7 and 3 are corresponding angles and they measure same as per property of corresponding angles, therefore:

m∠3 = m∠7
m∠7 = 180° - m∠8 = 180° - 108° = 72°
So m∠3 = 72°

Option D is correct

Explain why 2/3 x 12 can be written as 2 x 12 divided by 3.

Inga [223]

Answer and Step-by-step explanation:

$\frac{2}{3}$ × 12 can also be written as $\frac{2 * 12 }{3}$ because the 12 is multiplying the numerator of the fraction.

12 can also be written as $\frac{12}{1}$ .

When we solve, this is what is happening:

$\frac{2}{3}$ × $\frac{12}{1}$

The 12 will be multiplying the 2, while the 1 will be multiplying the 3. Because 3 times 1 is 3, we don't show the 1. So, that can leave us with 2 being multiplied by 12 in the numerator.
