Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)
Answer:
134.2258
Step-by-step explanation:
The side in front of 41 degree can be found using Sine formula, 19/sin(60)=x/sin(41), x=14.4. Next the missing angle is 79 degrees. The area of triangle in this case is (14.4*19)*sin(79)/2=134.2258
The number is seven because 7×7 = 49 and 49-3 = 46
Answer:
Weight of Large Box = 18.5 kg
Weight of Large Box = 13.25 kg
Step-by-step explanation:
<u>Given:</u>
There are two types of boxes i.e. Large and Small
Let the weight of Large boxes = L kg
Let the weight of Small boxes = S kg
As per given statement:
- A delivery of eight large boxes and four small boxes has a total weight of two hundred and one kilograms.
Writing equation for above:
....... (1)
- A delivery of three large boxes and two small boxes has a total weight of eighty two kilograms.
Writing equation for above:
Now, by solving the equations (1) and (2), we can get the values of L and S.
<em>Multiplying equation (2) with 2 and subtracting from equation (1):</em>
-
-
--------------------
L = 18.5 Kg
Putting value of L in equation (1):
So, the answer is:
Weight of Large Box = 18.5 kg
Weight of Large Box = 13.25 kg
Answer: 10
Step-by-step explanation:
Use Pythagorean theorem!
a^2+b^2=c^2
6^2+8^2=c^2
64+36=c^2
100=c^2
Take the square root of 100 and you get c=10
