Ella has 3 apples. brad has 2 apples. sarah has 8 apples. how many apples do they have altogether?
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
Answer:
∠ U = 22.62°
Step-by-step explanation:
We can use the trigonometric expression to find ∠U by using the ratio:
sin(θ) = opposite/ hypotenuse
=> sin ∠U = 7.5/ 19.5
=> ∠ U =
( 7.5/ 19.5)
∴ ∠ U = 22.619° ≈ 22.62°
This is a pythagorean triple --> 3-4-5
Although you notice it is doubled but with the same pattern --> 6-8-10
Thus, the hypotenuse is 10.
The answer too 2 plus 2 is 4 because if you have 2 finger and add 2 more up it will be 4
