Answer:
40° and 140°
Step-by-step explanation:
A linear pair of angles sum to 180°
let x be one angle then the other is 3.5x and summing gives
x + 3.5x = 180
4.5x = 180 ( divide both sides by 4.5 )
x = 40
one angle = 40° , the other is 3.5 × 40° = 140°
Answer:
hmm not sure because you cant rlly solve for anything if there is a number but maybe try a+a=2a? because 2 a's just equal 2a but its still not rlly solving anything but it could work
Step-by-step explanation:
The middle term of the simplified product is “x”.
The simplified product is x^2 - x - 12
X being the middle
hope this helps !
Answer:
B. -√13/4
Step-by-step explanation:
cos 0 = -√3/4 => x=-√3 , h=4
tan 0 > 0
y should be on quadrant III
y= √4²-3= √16-3=√13 => -√13
so, sin 0 = y/h = -√13/4
