Step-by-step explanation:
The expression given is: sec β - cos β ( i will write "beta" instead of the symbol β)
<em>We know that
</em>
<em>Substituting this into the the expression and doing some algebra manipulation, we have:</em>

<em>Using the identity
(also
), we can now write:</em>

<em>We know
, substituting this, we have:</em>

Answer choice E is the right answer.
Answer:
x = 5
Step-by-step explanation:
GE is the angle bisector of quadrilateral DEFG,
Thus, by angle bisector property:
9x°= (5x + 20)°
9x = 5x + 20
9x - 5x = 20
4x = 20
x = 20/4
x = 5
All 3 angles are the same, the sides are just shorter as the object has been made smaller
