Answer:
x= 90 degrees because AD is the perpendicular bisector and the angle bisector
y=86 degrees because 47+47+86=180
Step-by-step explanation:
(3)(-5x+y=-3)
(5)(3x-8y=24)
-15x+3y=-9
15x-40y=120
3y=-9
-40y=120
-37y=111
Divide both sides by -37
y=-3
To solve for x. Choose one equation from the given and plug what you get in Y.
I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5
Hope, this helps.
Using SOHCAHTOA and Kenui's height and angle of depression (which is the downward angle from the horizontal ) the answer should be:
because its the Adjacent and Opposite sides use Tan;
Tan(6.8) = o/a
tan(6.8) = Distance / 219
tan(6.8)(219 = Distance
26.114 m
But because the angle of depression is the downward angle from the horizontal the answer may be Tan(83.2)(219) = 1836.589
the 83.2 coming from 90 degrees - 6.8 degrees
either way i"m still unsure because I don't see a need for the two angles or Mias involvement, sorry if I'm wrong
Answer:
3.8 = 38/10
Step-by-step explanation:
The given number = 3.8
We have to write 3.8 in fraction form a/b
Here we have 1 digit after the decimal. To get rid off the decimal number, we need to multiply both the numerator and the denominator by 10 since we have to 1 digit after the decimal.

= 38/10
Therefore, the answer is 3.8 = 38/10
Thank you.
