The measure of the ∠Q = 41°
By law of cosines:
a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.
Which can we stated as:
solving equation using normal algebra:
60cos(Q) = 36 + 25 - 16
60 cos(Q) = 45
cos(Q) = 45/60
cos(Q) = 3/4
Thus, Q = 41°
Hence, the measure of the smallest angle in a triangle whose sides have lengths 4, 5, and 6. ∠Q is 41°.

Answer:
y=x-3
Step-by-step explanation: In order to find the slope, you must find out what y is. So you move the 3 to the other side and it becomes negative. thus, the answer is y = x -3

Answer:
The correct option is A.
Step-by-step explanation:
Braxton is testing 2 different types of motor oil in his truck to determine which one will last longer.
Now, he adds Brand A to the truck and Brand B to his sister's car.
Now, as Braxton wants to test the motor oil in his truck so there is no need of adding the motor oil to his sister's car as by doing so he cannot result in to a meaningful conclusion.
So, Braxton need to add both the motor oil into his truck one by one.
Hence, The conclusion of Braxton is not valid because he added Brand B to his sister's car, not the truck.
Therefore, The correct option is A.
