Answer:
(2)
Step-by-step explanation:
Having three of the same angles ("AAA") does not prove that two triangles are congruent. All the other options use one of the viable methods (SSS, SAS, ASA, AAS).
The speed of the ball is
ds/dt = 32t
At t =1/2 s
ds/dt = 16 ft/s
The distance from the ground
50 - 16(1/2)^2 = 46 ft
The triangles formed are similar
50/46 = (30 + x)/x
x = 345 ft
50 / (50 - s) = (30 + x)/x
Taking the derivative and substituing
ds/dt = 16
and
Solve for dx/dt
Answer:
p = -3
Step-by-step explanation:
-2 (p - 5) + 7p = -5
-2p + 10 + 7p = -5
5p = -15
p = -3
Answer:
X = 64
Step-by-step explanation:
Comparing the two triangle put the right angle into consideration.
(17 + X)/(X + 8) = (X + 8)/X
Cross multiplying
X(17 + X) = (X + 8)(X + 8)
17X + X^2 = X^2 + 8X + 8X + 64
Collecting like terms
X^2 - X^2 + 17X - 8X - 8X = 64
X = 64
Let, the width = x
Then,Length = 2x
Now, Area = l * w
A = (2x)(x)
128 = 2x²
x² = 128/2
x = √64
x = 8
In short, Your Answer would be 8 Feet
Hope this helps!
