Answer:
22
Step-by-step explanation:
15-(-7)
15+7=22
The evaluation is (2sin2∅-cos2∅)sec2∅.
<h3>What are trigonometric functions?</h3>
Trigonometric functions are functions used to relate the sides of a triangle with its angles.
Analysis:
2tan2∅ -(1- tan2∅)
2tan2∅ - 1 + tan2∅
3tan2∅ - 1
3() - 1
(3sin2∅/cos2∅) - 1
(3sin2∅ - cos2∅)/cos2∅
but 1/cos2∅ = sec2∅
(3sin2∅ - cos2∅)/sec2∅

Depending on the way that they are lined up
I believe it is reflection across the Y-axis, followed by reflection across the X-axis.
Reflection is the mirror image of the shape across an axis.
Translation is the sliding down or up of the shape.
