Answer:
\angle ACB=40^{\circ}, \angle ABC=63^{\circ}
Step-by-step explanation:
Finding x:
We know that 
, because it's a straight line. So, 
.
We know that the sum of the angles of any triangle will be 
.
So, we have that 
.
Combining like terms on the left gives 
.
Subtracting 
from both sides gives 
.
Dividing both sides by 
gives 
.
Finding missing angle measures:
.
.
So, 
and 
and we're done!
Note: 
. Coincidence? If not, try and prove it!
Answer:
C. 40
Step-by-step explanation:
average = (42 + 35 + 51 + 32)/4 = 40
Answer: C. 40
Answer:
Its acceleration will be 25m/s^2
Step-by-step explanation:
Distance the drag star moved from rest =400meters
Time taken =4 seconds
Speed= velocity= distance/time= 400m/4 s=100m/s
Acceleration at time 4 seconds will be;
Acceleration = Velocity/time=100/4=25m/s^2
Answer:
Step-by-step explanation:
Your answer
Assume that
Sammie is x,,,, Jennie is 9 years younger than him. So, Jennie ( y) = x-9
According to second condition eq is
(X-5) = 4(y-5)
Place the value of y in eq 2
You will find x= 17
Put x in eq 1
Y = 8
Answer:
4 1/2 days
Step-by-step explanation:
<u>cows | 6 | 9</u>
<u>days | 3 | </u><u> x</u>
6 divided by 2 is 3
9 divided by 2 is 4.5
x = 4 1/2 days
