No, when you plug is -5 for x and -1 for why, it ends up being -9 not -11. (-5,-1) is not a solution.
The Exact Square Root Is: 4.58257569496
Estimate Is: 5
Answer:
sin θ = 
Step-by-step explanation:
Given that,
cos θ = 
From the trigonometric functions,
cos θ = 
⇒ adjacent = 
, and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
= 
+ 
= 
+ 
9 = 3 +
= 9 - 3
= 6
x = 
Thus, opposite side =
So that,
sin θ = 
=
Therefore,
sin θ =
Solve for m.
Add 7 to both sides to get 3m=15
Then divide by sides by 3 to get m=5.
The final answer is m=5.
Answer:
C. 42 yards
Step-by-step explanation:
You may recognize this as a 3-4-5 right triangle with a scale factor of 14. The two given sides are 5·14 = 70 and 4·14 = 56. Then the missing side is 3·14 = 42.
If not, you can use the Pythagorean theorem in the usual way:
... hypotenuse² = leg1² +leg2²
... 70² = 56² +leg2²
... leg2 = √(70² -56²) = √1764 = 42 . . . . yards
The cable is anchored 42 yards from the base of the tower.
