X-y=-4 is the equation for question listed above, no direct variation.
Answer:
65 degrees
Step-by-step explanation:
Break the parallelogram up into two triangles. Angle E is 70 degrees and 45 degrees because of the property of equal opposite angles. So E 45 degrees Y 70 degrees and if you add the two up you get 115 degrees. There are 180 degrees in a triangle, so 180-115=65.
Answer:
8
Step-by-step explanation:
mystery number= x
he divdes x by 2 and then subtracts 9 and gets -5. reverse the order to find x.
-5+9 which is 4 times 2 which is 8. x is 8
Answer:
I think 42 ;-; sorry if I'm wrong lamo
Step-by-step explanation:
Answer:
x = 26.4°
Step-by-step explanation:
Defence angle = x
Side length Opposite to reference angle = 4
Hypotenuse length = 9
Apply trigonometric ratio, SOH. Thus:
Sin x = Opp/Hyp
Sin x = 4/9
![x = sin^{-1}(\frac{4}{9}](https://tex.z-dn.net/?f=%20x%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B4%7D%7B9%7D%20)
x = 26.3878° = 26.4° (nearest tenth)
