Answer:
<A= 47, <B= 90, <C= 43
Step-by-step explanation:
2x +3 + 4x + 2 + 2x-1 = 180
8x + 4= 180
8x = 176
x =22
2x+3= 44+3= 47
4x+2 = 88+2 = 90
2x-1= 44-1 = 43
Answer:
a =12*sqrt(2)
Step-by-step explanation:
3. The Pythagorean theorem states
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +21^2 = 27^2
a^2 +441 =729
Subtract 441 from each side
a^2 +441-441 = 729 -441
a^2 =288
Take the square root of each side
sqrt(a^2) = sqrt(288)
sqrt(xy) = sqrt(x)sqrt(y)
a = sqrt(144)sqrt(2)
a =12*sqrt(2)
Y=2x-6 (4, 3)
(X, Y)
3=2(4)+b
3=8+b
-5=b
Y=2x-5
7 Did occurred twice. So 7 is the mode.
This is a linear equation with y-intercept $50 and slope $0.25/mile:
TC = $50 + ($0.25)x, where x is the number of miles driven.
