Answer:
![m\angle 2=33^\circ](https://tex.z-dn.net/?f=m%5Cangle%202%3D33%5E%5Ccirc)
Step-by-step explanation:
<u>Right Triangle</u>
The figure shows a right triangle with angles 2 and 3 unknown.
The sum of the internal angles of all triangles is 180°, since one of them is 90°, then the sum of the rest of the angles is 90°. It means that:
![m\angle 2+m\angle 3=90^\circ](https://tex.z-dn.net/?f=m%5Cangle%202%2Bm%5Cangle%203%3D90%5E%5Ccirc)
The measures of both angles are expressed as functions of x. Substituting their values:
x+8 + 2x + 7 = 90
Simplifying:
3x + 15 = 90
Operating:
3x = 90 - 15 = 75
Solving:
x = 75 / 3 = 25
x = 25°
Now, the measure of angle 2=x+8 = 33°
![\boxed{m\angle 2=33^\circ}](https://tex.z-dn.net/?f=%5Cboxed%7Bm%5Cangle%202%3D33%5E%5Ccirc%7D)
The sum of all three is 6x^2y + 2xy^2
Answer:
5, 5+ 5(1/5) 5 is the number
Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14)
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
