Answer:

Step-by-step explanation:
y can be found using the Law of sines as explained below:
m < Y = 106°
m < X = 58°
WY = x = 8
WX = y = ?
Thus,



Multiply both sides by 0.961 to solve for y




(to the nearest tenth)
I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.



Answer: n² - 3n - 20 = 0
That doesn't factor so there is no integer n solution.
That means there are no polygons with 10 diagonals.

It’s like the answer you have to figure out ? Lol idk
Answer:
los ceros de una función también se pueden llamar las raíces, básicamente significan donde una función o parábola cruzará la coordenada x. encontrar las raíces de una ecuación significa encontrar donde la parábola intercepta el eje x
Step-by-step explanation:
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°.

The other two angles are 40° and 100°.
