Answer:
x° = 78°
Step-by-step explanation:
x° is the measure of external angle BHC of triangle BHD. As such, its measure is the sum of the opposite interior angles at B and D:
47° + 31° = x° = 78°
For 25, I would begin with working out the difference in price.
$450 - $360 = $90
Then, $450 is 100% of the cost, therefore we want to know how much it has decreased.
I would work out 1% of $450. [$450 / 100 = $4.50]
Now if we divide $90 (the change in cost) by $4.50, we can tell what percent of a decrease we have.
90 / 4.5 = 20
Therefore we have a 20% decrease.
