Step-by-step explanation:
( secA + 1)( sec A - 1)
Using the expansion
( a + b)( a - b) = a² - b²
Expand the expression
We have
sec²A + secA - secA - 1
That's
sec² A - 1
From trigonometric identities
<h3>sec²A - 1 = tan ²A</h3>
So we have the final answer as
<h3>tan²A</h3>
As proven
Hope this helps you
X might equal 5 because if you replace X with 5 the problem makes since....X - 2 = 3....(5) - 2 = 3
Answer:
b < 10
Step-by-step explanation:
-b - 2 > 8
Add 2 to both sides.
-b > 10
Divide both sides by -1. When dividing by a negative, flip the inequality sign.
b < 10.
4 degrees.
Divide 20 by 2 to get 10, subtract 6.
Answer:
It is < (less than sign)
Step-by-step explanation:
Negative numbers when they keep going up, (-11,-12,-13) they actually become less, not greater. Also heres a tip: If you see the arrows in a number line compared to these signs, try to remember them as good help cause sometimes I get confused then remember. (>,<)
