Hey there!
A quadrilateral has 360 degrees. So add all the degrees together to 360. 9x+1+5x-12+8x+61+90=360. 90 degrees is in the bottom left corner. Combine like terms. 22x+140=360. Subtract 140 from each side. 22x=220. Divide 22 on each side to get x=10. Plug in 10 for x in angle D. 5(10)-12=38. The measure of angle D is 38 degrees.
I hope this helps!
Answer:
Step-by-step explanation:
When you have a number (17) and want to know some fraction (2/5) of that number, you should multiply the number by the fraction.
17 * (2/5)
= (17*2)/5
= 34/5
= 6.8
You can then round this number up --> about 7 cars.
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
