Answer:
20
Step-by-step explanation:
constant is the term with no variables attached
A=1, c=25/7(3.571429) b=?
c=hypotenuse
a=side
In this case, we are finding for a SIDE and not the HYPOTENUSE.
Using Pythagoras' theorem
side²= hyp²–side²
b²= 3.57²–1²
b²= 12.7–1
b²= 11.7
b²= √11.7
b²= 3.4(correct to 1 dp)
Therefore, b= 3.4

Answer:
its 58 degreese F
Step-by-step explanation:
start with 9*2 and that equals 18 then you subtract 18 from 76 which equals 58. that is your answer 59 degrees F
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
