Answer:
32° + (x+9)° + (2x-8)° = 90°
32° + x + 9° + 2x - 8° = 90°
33° + 3x = 90°
3x = 90° - 33°
3x = 57°
x = 19°
angleCFD = 2×19 - 8
angle CFD = 30°

Answer:
All four restrictions apply:
m not= 0
n not= 0
m not= -4n
n not= m/-4
Step-by-step explanation:
For a rational expression, any expression that is a denominator AT ANY POINT in the calculation, must have the appropriate restrictions applied. There are two different expressions, mn and m+4n that we are concerned about here. See image. All four restrictions must be applied.
Answer:
sorry i dont have the answer i just need points
Step-by-step explanation:
Answer:
x = 4
, y = 2![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
x = 4![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
-------------------------------------------------------------------
Using the tangent ratio in the right triangle and the exact value
tan30° =
, then
tan30° =
=
=
( cross- multiply )
y = 2![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
