Hello :
<span>the opposite is : -6
</span><span>the absolute value is : 6</span>
Sin θ = 2 / 7
tan θ > 0
cos θ = ?
sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse
short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?
adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5
cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7

Answer:
pos: 99. Sor: 17. roq: 64
Step-by-step explanation:
(5x+4)+(x-2)+(3x+7)=180
we add the angles to 180 because straight lines are equal to 180
5x+4+x-2+3x+7=180
5x+x+3x+4-2+7=180
9x+9=180
9x=
9x=171
x=19
then we plug x in
5(19)+4 + (19)-2 +3(19)+7 = 180
angles (left right)
99. 17. 64.
