Answer:
Answer: (1) The measure of angle T is 100 degrees --> since no other angle can be equal to 100 degrees (because in this case the sum of the angles will be more than 180 degrees) then the other two angles, R and S, are equal: R=(180-100)/2=40.Mar 21, 2020
Step-by-step explanation:
Steps to solve
1) We have 5 +(-8)n = 29, which we can change to 5 - 8n = 29, because a positive times negative equals a negative
2) To isolate n, we move all of the other numbers to the other side of the equation. Since 5 is the only number on the left side, we subtract 5 from both sides
5 -5 - 8n = 29 -5
-8n = 24
3) Now, to find n, we want to just have one n on the left side instead of -8, so we divide the equation by -8 to find that
-8n/-8 = 24/8
n = 3
Therefore, n = 3
Step-by-step explanation:
LHS= 1 + cot^2A/1+cosecA
=(1+cosecA + cot^2A)/1+cosecA
{By using basic trigonometric theorem cot^2A = cosec^2A - 1}
=(1+cosecA + cosec^2A - 1)/(1+cosecA)
=(cosecA + cosec^2A)/(1+cosecA)
=[cosecA (1+cosecA)]/(1+cosecA)
{Cancelling 1+cosecA}
=cosecA
4x^2 + 9xy - y^2 = 8
8x + 9xf'(x) + 9y - 2yf'(x) = 0
f'(x) (2y - 9x) = 8x + 9y
f'(x) = (8x + 9y)/(2y - 9x)
