Answer:
3/2 =x
Step-by-step explanation:
1/8 = x/12
Solve using cross products
1 * 12 = 8x
12 = 8x
Divide each side by 8
12/8 =8x/8
3/2 =x
One hour and thirty minutes
<u>Answer:</u>
<u>Step-by-step explanation:</u>
The sum of interior angles of a quadrilateral is 360°.
If we consider the measure of one of the unknown angles to be
°, we can set up the following equation:

Now we can solve for
:
⇒ 
⇒
[subtracting 192° from both sides]
⇒ 
⇒
[dividing both sides by 2]
⇒ 
Therefore, the other two angles each have a measure of 84°.
