13POINTS!!!

Answer:

When we know all 3 sides we use the law of cosines

a = 47  

b = 11  

c = 38

cos (A) = (b^2+c^2-a^2)  / (2bc)

cos (A) = -0.7703349282

Angle A = 140.38

cos (B) = (a^2 + c^2 -b^2) / (2ac)

cos (B) =  0.9888017917

Angle B = 8.5826  degrees

cos (C) = (a^2 + b^2 -c^2) / 2ab

cos (C) = 0.8568665377

cos (C) = 31.033 degrees

Angle W would be the smallest angle so it equals

31.033 degrees or rounded to nearest tenth

31.03

How do you get answer for the equation y-3.7=4.2
xz_007 [3.2K]
All you need to do is add 3.7 to the other side and since you don't need to divide anything from y, whatever you get will be your final answer. :)

Goshia [24]
(10x+5)4 = 30x + 3x + 6x +30

40x + 20 = 39x + 30

X = 10

perimeter of the square= 420
perimeter of the triangle= 420

Which equation represents a slope of −4<br> and y-intercept of (0, 2) ?
aksik [14]

Answer:

y = - 4x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 4 and y- intercept = (0, 2) ⇒ c = 2

y = - 4x + 2 ← equation in slope- intercept form
