Answer: 8
Step-by-step explanation:
I took the test and I got it right.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
cosec x =
Consider left side
=
=
= cosec x = right side ⇒ proven
Answer: x = 44
Step-by-step explanation:
The exterior angles of a polygon add to 360 degrees so:
- (3x+4)+(3x+4)+29+34+25=360 [forming equation]
- 6x+96=360 [combine like terms]
- 6x=264 [subtract 96 from both sides]
- x = 44 [divide both sides by 6]
Tanya would be 14 because jassica is 5 and 5x3=15-1=14
Move all terms to the left side and set equal to zero. then set each factor equal to zero. x=1,-3
