Answer:
see attached
Step-by-step explanation:
The attachments show the initial (brown) and final (blue) positions of the phone. The spreadsheet shows all the intermediate locations and the formulas used to determine them.
The two reflections cancel the total of 180° of CW rotation, so the net result is simply a translation. That translation is up by 9 units.
__
Translation up adds to the y-coefficient; translation right adds to the x-coefficient. Down or left use negative values.
90° CW does this: (x, y) ⇒ (y, -x)
Reflection across y does this: (x, y) ⇒ (-x, y)
Reflection across x does this: (x, y) ⇒ (x, -y)
Answer 145°
Step-by-step explanation:
( 5x+5 ) + 40° = 15x - 5
[ Reason : exterior extended angle of a triangle is always equal to the sum of two non adjacent interior angles ]
( 5x+5 ) + 40° = 15x - 5
i.e, x= 10°
put this value of x on <PGF
= 15x - 5
= 15 * 10 - 5
=145°
Answer:
15.4
Step-by-step explanation:
3(9+3⋅8)−23
3(12.8)-23
38.4-23
15.4
So the answer is15.4
Y= 15
x = 15 rad 2 i think
Basically it’s r=c/2pi meaning it’d be r=62/2(3.14) which would give you r=9.87
