5x = 18
Answer:
5,4
Step-by-step explanation:
here is the rule (4,-5) rotate 90 clockwise = (5,4)
4,-5 will put you in the 4 quadrant rotate it 90 clock wise Put you in the first quadrant

According to given figure, The Triangle BDC is a right angled Triangle (Angle D = 90°)
So, we can apply Pythagoras theorem to find the Side a (Hypotenuse)
Now, let's solve ~
Therefore, Length of side a is 5 units ~
Answer:
84°
Step-by-step explanation:
since the opposite side looks identical to the first angle, the second would be the same degrees.
