Answer:
Step-by-step explanation:
Perimeter of the trapezoid-shaped window = sum of all the sides of the window frame
Thus, the equation to find the unknown side length, x, would be:
✔️
Solve for x
Subtract 14.89 from each side
✔️
Answer:
Re = 6.2
Im = 37
Step-by-step explanation:
Re is the Real Axis which is the real number in the equation (6.2).
Im is the Imaginary Axis which is the imaginary number in the equation (37)
Step-by-step explanation:
what is the main condition the lengths of the sides of a right-angled triangle have to fulfill ?
Pythagoras !
c² = a² + b²
c is the Hypotenuse (the baseline opposite of the 90 degree angle), a and b are the so-called legs (the sides enclosing the 90 degree angle).
only if there is a combination of the sides, for which the Pythagoras equation is true, do we have a right-angled triangle. otherwise not.
we also know CA = 18 - 7 - 3 = 8 cm
so, let's try
8² = 7² + 3²
64 = 49 + 9 = 58 wrong
7² = 8² + 3²
49 = 64 + 9 = 73 wrong
3² = 8² + 7²
9 = 64 + 49 = 113 wrong
so, there is no combination, where the Pythagoras equation is true, so it is NOT a right-angled triangle.
your options are Put the point of the compass on point B and the pencil point on point C. With the compass point still on B, draw two arcs that intersects the circle with center A.
Use a straightedge to join the four points where the circles intersect.
Draw and label the points where the circles with centers A and B intersect and where the circles with centers A and C intersect.
Put the point of the compass on point B and the pencil point on point C. Using this compass width, put the compass point on A and draw another circle.
