The area of a triangle can be found by multiplying the base times half of the height.
Good Luck! Hope I helped:)
Answer:
x = y = 2
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
x = 2 ( divide both sides by )
x = 2
The triangle is isosceles, base angles both 45°, then legs are congruent, so
x = y = 2
Here’s my working out the green numbers are the answers
Answer:
12 hours
Step-by-step explanation:
Let the larger pipe can drain the tank in x hours
Than, time taken by smaller tank to drain the tank= (x+6) hours
If working togather, both pipe can drain the tank= 4 hours
A.T.Q
+ =
=
=
8 x +24= + 6 x
- 2 x- 24= 0
-6 x+ 4 x -24=0
x(x-6) + 4(x-6)= 0
(x-6)(x+4)=0
X= 6, X=-4 is rejected
Hence, time taken by larger tank to fill the drain= 6 hours
Hence, time taken by smaller tank to drain the tank = 6+6= 12 hours
Hence, the correct answer is 12 hours
