Answer:
See below.
Step-by-step explanation:
In all triangles, the three interior angles will add up to 180°. Therefore:
![(9x+6)+(5x)+(90)=180](https://tex.z-dn.net/?f=%289x%2B6%29%2B%285x%29%2B%2890%29%3D180)
Remember that the little square means a right angle.
Now, solve for <em>x</em>.
![9x+6+5x+90=180\\14x+96=180\\14x=84\\x=6](https://tex.z-dn.net/?f=9x%2B6%2B5x%2B90%3D180%5C%5C14x%2B96%3D180%5C%5C14x%3D84%5C%5Cx%3D6)
Now, plug <em>x </em>back into the equations to find each angle:
1)
![\angle ABC = \angle B = 9(6)+6=60\textdegree](https://tex.z-dn.net/?f=%5Cangle%20ABC%20%3D%20%5Cangle%20B%20%3D%209%286%29%2B6%3D60%5Ctextdegree)
2)
![\angle BCA = \angle C = 90\textdegree](https://tex.z-dn.net/?f=%5Cangle%20BCA%20%3D%20%5Cangle%20C%20%3D%2090%5Ctextdegree)
3)
![\angle CAB = \angle A=5(6)=30](https://tex.z-dn.net/?f=%5Cangle%20CAB%20%3D%20%5Cangle%20A%3D5%286%29%3D30)
I rounded so 9.29
good night!!
Answer:
<em>(3 , 1)</em>
Step-by-step explanation:
(3 , - 3)
(3 , - 3 - 2 + 6) = <em>(3 , 1)</em>
Answer:
C. 49
Step-by-step explanation:
When you put the equation together it becomes: 7(9)-14=49
Answer:
6
Step-by-step explanation:
3x+6+5x+10=64
3x+5x+6+10=64
8x+16=64
8x=64-16
8x=48
divide both sides by 8
x=6
