10 I think cause if they have 13 in total & ask for 3 then 13-3=10
Answer:
20°
Step-by-step explanation:
1) Opposite angles are equal, so the opposite will be 140°.
2) Then, you do 140+110+90+90 (since A and D are at right angles) which gets you 430°
3) Finally, since its a pentagon, you do 540° - 430° which is 110°
Answer:
1 × 10² J
Step-by-step explanation:
Given data
2 oz × (1 kg/35.274 oz) = 0.06 kg
The work exerted by the player is equal to the kinetic energy (K) adquired by the ball.
K = 1/2 × m × v²
K = 1/2 × 0.06 kg × (57.7 m/s)²
K = 1 × 10² J

Answer:
Step-by-step explanation:
L= length
w= width= L-3
A= area= 238 ft^2
LENGTH
Area Formula
A= LW
substitute w value
238= (L)(L- 3)
multiply L by parentheses
238= L^2 - 3L
subtract 238 from both sides
0= L^2 - 3L - 238
factor
0= (L + 14)(L - 17)
set each parentheses equal to 0
0= L + 14
-14= L
OR
0= L - 17
17 ft= L
*Since the measure of a rectangle would not be negative, L= 17 ft
WIDTH
w= L - 3
w= 17 - 3
w= 14 ft
ANSWER: Length= 17 ft; Width= 14 ft
