Answer:
Slope-intercept form
y=7x-16
Step-by-step explanation:
<h3><u>Answer</u> :</h3>
For triangle : A + B + C = π
⇒ A + B = π - C
⇒ cot(A + B) = cot(π - C)
⇒ 
⇒ 
<u>Now 1st part of the given expression</u>!
⇒ 
⇒ 
⇒ 
⇒ 1 - cotB cotC
<u>Similarly 2nd part</u>!
⇒ 1 - cotA cotB
<u>Similarly 3rd part</u>!
⇒ 1 - cotC cotA
<u>LHS</u> :


= <u>RHS</u>
<h3>Hence Proved!!</h3>
Answer:
(3x-8)
Step-by-step explanation:
6x^2-13x-8=(3x-8)(2x+1)
Thus, (3x-8) is one of the factors of the formula.
Answer:
122.5 degrees
Step-by-step explanation:
A six sided polygon's interior angles sum to
(n-2)(180) = (6-2) (180) = 720 degrees
then x + x + x + x+10 + 130 + 90 = 720
4x = 490 so x = 122.5 degrees
