Answer:
3.25 or 3 1/4 inches
Step-by-step explanation:
A = lw
22.75 = 7w
w = 3.25 which is 3 1/4
Answer:
x = 60 degrees
Step-by-step explanation:
1. We know that a triangle has a total angle of 180. If we look at the image closely, triangle GEH can be found, and since we know two angles, which are 40 and 80, we can find the other angle. 180 - (40+80) = 60. Angle GEH is 60 degrees.
2. If angle GEH is 60 degrees, angle EFD will also be 60 degrees, since they have the same angle side. To prove this, we can use alternate interior angles. This means that if a line crosses two parallel lines, the inner angles made have the same size.
3. Since angle EFD is x, we can find that x is equal to 60 degrees.
You will try all the cases and see if all the equations will match after substituting or no.
1.
5x
put x = 1/2
2.5 isn't equal to 20
4=15x
put x =1/2
15 × 1/3 =7.5
7.5 isn't equal to 4
-4x = 60
put x = 1/2
-4×1/2 = -2
-2 isn't equal to 60
30 = 60x
pit x = 1/2
60 × 1/2 = 30
30 = 30
Therefore, the correct answer is D. 30 = 60x
2. Answer is B. -4 , 4
Put x = -4
l 5 × -4 l = l-20l = 20
20 = 20
Put x = 4
l 5 × 4 l = l20l = 20
20 = 20
Answer:
See below
Step-by-step explanation:
The result of the calculation of area ( L x W ) should have no more significant digits than the lowest factor ....in this case 75 has only TWO significant digits...... the naswer should have the same ...two
75 * 50.3 = ~3800 cm^2
