Answer:
Use the Triangle exterior angle theorem. The definition of this theorem, is that the exterior angle you are solving for is the sum of the two opposite interior angles. Set the equation:
80 + x = 3x - 22
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x and add 22 to both sides.
80 (+22) + x (-x) = 3x (-x) - 22 (+22)
80 + 22 = 3x - x
Simplify.
102 = 2x
Isolate the variable, x. Divide 2 from both sides.
(102)/2 = (2x)/2
x = 102/2
x = 51
Check. Plug in 51 to the equation given.
80 + x = 3x - 22
80 + (51) = 3(51) - 22
131 = 153 - 22
131 = 131 (True).

Answer:
(3,-2), (-3,-7), 2nd one is x2,y2

Answer:
csc (0°) and sec (90°) are not defined.
Step-by-step explanation:
Given the options wehave to select the option which is undefinesd
First option: sec 45°
which is defined
Second option: csc(0°)
which is not defined
Third option: sec(90°)
which is not defined.
Hence, option 2 and 3 are not defined.
Answer:
When subtracts fractions with the same denominator, you only have to subtract the numerator.
5/9-3/9=
The denominators are the same, you just have to subtract the denominator. So in this case, you would only need to subtract 5-3. Therefore the answer would be 2/9. (Simplify if needed.)
Hope this Helps!
