Answer: <b is 59.3 degrees
Step-by-step explanation:
Triangles have total of 180 degrees
The bottom two points are both 4y
To solve: 4y+4y+(3y+14)=180
11y+14=180
-14
11y=166
Divide by 11
Y=15.1
So plug that in for y
3(15.1)+14=B
59.3

Answer:
2L^2 - 27L + 70 = 0.
Step-by-step explanation:
p = 2(L + W)
27 = 2L + 2W
2W = 27 - 2L
W = (27 - 2L)/2
Substitute for W in the area equation:
A = LW
35 = (27 - 2L) * L / 2
L(27 - 2L) = 70
-2L^2 + 27L - 70 = 0 Multiply through by -1:
2L^2 - 27L + 70 = 0
Answer:
24 units³
Step-by-step explanation:
Formula:
Volume (V) = length (l) × width (w) × height (h)
V=3×4×2=24 units³
Answer:
A = 50
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
A+B+C =180
2x-10 + 70 + x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x +90-90 = 180-90
3x= 90
Divide each side by 3
3x/3=90/3
x =30
We want to find A
A =2x-10
= 2*30 -10
=60-10
=50
The answer is D. If you divide 1000 by 100, it is 10. 10 is equal to 1/100 of its previous value of 1000.
