Answer:
2.3
Step-by-step explanation:
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:
B(3,8)
Step-by-step explanation:
M(0,6) A(-3,4) B(x,y)
0=
6=
0=-3+x 12=4+y
x=3 y=8
B(3,8)
46.6 billion
explanation:
Isolate S on the left side by adding 1.9x to both sides. this gives you S = 4.8 + 1.9x. Plug in 22 for x because 2020 is 22 years from 1998.
4.8 + 1.9(22) = 46.6
