The answer to this is 65.
Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180.
First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180.
180-148=32. x=32.
Then we plug that in the expression for angle a.
2x+1 becomes 2(32)+1
2*32=64
64+1=65.
a=65
Answer:
Step-by-step explanation:
The distance that you travelled in your hummer between Olympia and Spokane is 319.4 miles.
You fill up your gas tank with 28.68 gallons of premium gasoline that costs $2.89 per gallon. This means that the total cost of premium gasoline that you bought would be
2.89 × 28.68 = $82.8852
your gas mileage in miles per gallon is 319.4/28.68 = 11.14 miles per gallon.
Therefore, if it costs $82.8852 to drive 319.4 miles,
then the cost of just one mile in your hummer would be
82.8852/319.4 = $0.26 per mile.
144-:-8= 18 Distributive Property to answer
Answer:
60 degrees
Step-by-step explanation:
We know that a right triangle is 90 degrees
We have one angle given of 30 degrees
90 degrees - 30 degrees (known angle) = 60 degrees (unknown angle)
Therefore the unknown angle is 60
