Answer:

$m\angle ABC = 35\degree$

Step-by-step explanation:

(3x - 70)° = x° (corresponding angles)

3x - 70 = x

3x - x = 70

2x = 70

x = 70/2

x = 35

$m\angle ABC = (3x - 70)\degree \\\\m\angle ABC = (3\times 35- 70)\degree \\\\m\angle ABC = (105- 70)\degree \\\\\huge\red {\boxed{m\angle ABC = 35\degree }} \\\\$

Multiple =4.

Multiply the numerator and the denominator by the multiple 4.

8×4/ 25×4.

Simplify.

32/100=0.32

Combine the whole number component with the decimal.

5+0.32=5.32

$\sf \dfrac{4}{5} \ \text{is in the simplest form}$

$\sf \text{Simplest form of $\dfrac{12}{20}$} = \dfrac{12 \div 4}{20 \div 4}=\dfrac{3}{5}$
