If you know the measure of one of the 8 angles, you can find the measure of all of the others. Try it. The measure of <1 = 12

MariettaO [177]

Answer:

$\angle 2 =60$

$\angle 3 = 60$

$\angle 4 = 120$

$\angle 5 = 120$

$\angle 6 = 60$

$\angle 7 = 60$

$\angle 8 = 120$

Step-by-step explanation:

Given

$\angle 1 = 120^\circ$

See attachment

Required

Determine the other angles

$\angle 1$ and $\angle 2$ are on a straight line.

So;

$\angle 1 + \angle 2 =180$

Make $\angle 2$ the subject

$\angle 2 =180 - \angle 1$

$\angle 2 =180 - 120$

$\angle 2 =60$

$\angle 1$ , $\angle 4$ , $\angle 5$ and $\angle 8$ are corresponding angles.

So;

$\angle 4 =\angle 1 = 120$

$\angle 5 =\angle 1 = 120$

$\angle 8 =\angle 1 = 120$

Similarly; $\angle 2$ , $\angle 3$ , $\angle 6$ and $\angle 7$ are corresponding angles.

So;

$\angle 3 =\angle 2 = 60$

$\angle 6 =\angle 2 = 60$

$\angle 7 =\angle 2 = 60$

Use a number line to compare the numbers. Which shows the correct symbol to compare the numbers? 1.2 1 1/5

Leno4ka [110]

For this case we must compare the following expressions:

$1.2\\1 \frac {1} {5}$

We convert the mixed number to a fraction:

$1 \frac {1} {5} = \frac {5 * 1 + 1} {5} = \frac {5 + 1} {5} = \frac {6} {5} = 1.2$

So, we have to compare:

1.2 and 1.2

It is observed that the expressions are equal, so we have the sign of equality "=":

$1.2 = 1.2$

Answer:

$1.2 = 1.2$
