Answer:
∠C = 37° ,
AB = 26.54 cm ,
BC= 33.27 cm
Step-by-step explanation:
Given that in triangle ABC
∠A = 39° AC = 20 cm
∠B = 104°
∵ sum of all the three angles of triangle = 180°
So, ∠C = 180° - ( ∠A + ∠B)
∠C = 180° - (39° + 104°)
∠C = 37°
Now Tan 37° =
Or, AB =
So, AB = 26.54 cm
Again, Sin 37° =
So, BC =
Or, BC =
∴ BC= 33.27 cm
Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer

C) (-1,8)
D) (0.5,5)
What is the solution to the system of equations?
y=2x-3.5y = 2 x − 3.5
x-2y=-14x − 2 y = − 14
Group of answer choices
(10.5, 7)
(-7, 3.5)
(7, 10.5)
(3.5, -7)
Answer:
Step-by-step explanation:
1. You can use the expression for y to substitute into the first equation:
2x +4(1/4x -3) = 12
2x +x -12 = 12 . . . . . . eliminate parentheses
3x = 24 . . . . . . . . . . . add 12; next divide by 3
x = 8 . . . . . matches choice C
__
2. You can use the expression for y to substitute into the second equation:
x -2(2x -3.5) = -14
-3x +7 = -14 . . . . . . eliminate parentheses
21 = 3x . . . . . . . . . . add 3x+14; next divide by 3
7 = x . . . . . matches the third choice
_____
When the answer choices are sufficiently different, you only need to find one value to determine which is the correct choice. (If you want to check your work further, you can substitute the other answer value into the two equations to see if it works.)
Answer:
P = 1.44 Watts
Step-by-step explanation:
We know that the relation between voltage and current in a simple circuit with a resistor is
V = I.R
Where
V = the voltage of the source
I = current of the circuit
R = resistance
The power is defined as
P = V.I
Which is the same as
P = V.(V/R)
P = (24 v)^2 / (400 ohm)
P = 1.44 Watts
