Answer:
3
Step-by-step explanation:
2a * 2a = A
2a * 2a = 36
we know that 6 * 6 = 36
so 2a would be equal to 2 * 6/2
so a = 3
Answer:
85 degrees
Step-by-step explanation:
To know the angle of the tower, we need to use the tower's length and the distance the object landed from the tower base to create a triangle, where the hypotenuse is the first one (55) and one cathetus is the other (4.8). The other cathetus is the tower height.
To know the angle that the tower leans from the ground, we know that its cossine will be 4.8 over 55 (adjacent cathetus over hypotenusa), so:
cos(angle) = 4.8/55 = 0.0873 -> angle = 85 degrees
Answer:
x=6, y=-6
Step-by-step explanation:
-4x-2y= -12
4x+8y= -24
comparing both equations and crossing out both 4x we get
6y= -36
y= -36/6
y= -6
now for finding x, take any one of those equations
we'll take 4x+8y= -24 for now other one would work too
4x+8(-6)= -24 (as y= -6)
4x-48= -24
x= 24/4
x= +6
