Answer:

80 is the answer

Explanation: angle CD=100

                    angle CA= 180-100      (linear pair)

                                    = 80

   

                      angle x = 80 (because when cbd = 100°, bfh = 100; therefore angle x=180-100 = 80

Mathematical Reason: if two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

Answer:

80 degrees, explanation down below

Step-by-step explanation:

according to the vertical angle theorem, two vertical angles are the same angle measure. so, angle CBD and angle ABF must be the same. this is 100 degrees. now, according to the corresponding angles theorem, corresponding angles are supplementary to each other (they add up to 180 degrees), so angle ABF and angle EFB are supplementary. since angle ABF is 100 degrees, we can subtract that from 180 degrees. therefore, angle x (same thing as EFB) is 80 degrees.

a salesman priced a four wheeler at $3,500 the first day it was on the market. The 2nd day he reduced the price by 10%.What was
Alex_Xolod [135]
The first step to solve this problem is to find 10% of 3,500. To do this you would set up the equation x/3,500=10/100. You then multiply 3,500 by 10, getting 35,000, then divide that by 100. The 10% would then be 350. Finally, you would subtract 350 from 3,500, getting 3,150 as your final answer.

PLEASE HELP ME! Would appreciate!

Answer: y = (1/2)x + 40

Explanation: use the formula ‘y=mx+b’

M is the slope, which is rise(or fall)/run. In this case it falls 1 and runs 2 so m=1/2

B is where the line intersects the y-axis so in this case it is 40

Put together it is y = (1/2)x + 40
