Answer: Yes and it could be greater than 5 but it has to be greater than 4
:
We know that
1+cot ²∅=csc² ∅
cot ∅=4/7
so
1+(4/7)²=csc² ∅
csc² ∅=1+(16/49)
csc² ∅=(65/49)
csc ∅=(√65)/7
remember that
csc ∅=1/sin ∅
sin ∅=1/csc ∅------> sin ∅=7/√65-----> sin ∅=(7√65)/65
the answer is
the best identity to find sin ∅ is
1+cot ²∅=csc² ∅
A) angle A = 180-135= 45 degrees
Angles A and 135 are supplementary angles
b) angle B= 135 degrees
because the two 135 angles are vertical angles ( opposite angles made by two intersecting line)
c) angle C = 45 degrees
because angles C and angles A are corresponding angles since line (1) and line (2) are parallel
The value of the expression 2n - 1 when n = 7 is 13.
<h3>Equation</h3>
2n - 1
when n = 7
- Substitute n = 7 into the equation
2n - 1
= 2(7) - 1
= 14 - 1
= 13
<h3>What is mathematical expression?</h3><h3 />
Mathematical expression is an expression which involves the combination of numbers and variables in a valid way, in a function of addition, subtraction, multiplication, division and exponentiation
Therefore, the value of the expression 2n - 1 when n = 7 is 13.
