x = 51.98
Step-by-step explanation:
tan 68 = opp/hyp = x/21
or
x = 21×tan68°
= 21(2.475)
= 51.98
Answer: y=32/5
Step-by-step explanation:
Calculate the number of hours between 4 PM and 10 AM:
4 PM to 4 AM is 12 hours.
4 AM to 10 AM is 6 hours
Total hours is 12 + 6 = 18 hours.
18 hours x 70 km/hr = 1,260 km total.
Answer:
Janelle's height is 82 units.
Step-by-step explanation:
Let j represent Janelle's height.
It is mentioned that, 58 is the difference between Janelle's height and 24.
Mathematically, we can write it as :
j-24 = 58
We can solve it as follows :
Adding 24 both sides,
j-24+24 = 58+24
j = 82
Hence, Janelle's height is 82 units.
Answer:
EBC and ABE, as well as ABD and ABE
Step-by-step explanation:
Supplementary angles form an 180 degree angle. In other words, they form a straight line.
EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.
EBC and ABE form a straight line. So they are supplementary angles.
ABD and ABE form a straight line. So they are also supplementary angles.
CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.
So, EBC and ABE, as well as ABD and ABE are the correct choices.
