Answer:
Ф = 
Step-by-step explanation:
It is a bit difficult to input the work here, so I uploaded an image
- First we can use the trig identities to change sec²(Ф) to tan²(Ф) + 1
- Then we can combine like terms
- Then we can factor this as a polynomial function
- Then we can set each term equal to zero and solve for Ф
- The first term tan(Ф) - 2 = 0 has no solution because tan(Ф) ≠ -2 anywhere
- The second term tan(Ф) - 1 = 0 has two solutions of
and 
so these are the solutions to the problem
Answer:
Trapezoid
Step-by-step explanation:
So there's four sides on a trapezoid. The top and bottom ones are parallel. But they're not congruent. I don't think... Anyway, good luck.
Answer:
ABC is more than 90 Degrees because it is an Obtuse Angle
ADC is less than 90 Degrees because it is an Acute Angle
I don't know the exact answer but I hope this helps you a little!

thats the answerrrrrrrrrrrrrrrrrrrr
Plug in -1 for x
h(-1) = 3(-1) + 4
h(-1) = -3 + 4
Solution: h(-1) = 1
