Answer:
145
Step-by-step explanation:
Angle 4 and 5 are the same.
Which means that angle 3 and 6 are the same.
A straight line has an angle of 180 degrees in total.
This means that we have to subtract 35 from 180.
This gives us 145.
So, the missing angle is going to be 145 degrees.
*also, 1, 4, 5, and 8 are the same angle.
**2, 3, 6, 7 are also the same angle.
***I just remember learning about this last year, don't remember what there called tho.
The unknown number . . . . . (z)
The sum of the unknown number and 22 . . . . . (z + 22)
The sum of the unknown number and 22
divided by the same unknown number . . . . . . . (z + 22) / z
You said that quotient is 12. (z + 22) / z = 12
Multiply each side by 'z' : (z + 22) = 12 z
Subtract 'z' from each side: 22 = 11 z
Divide each side by 11 : 2 = z .
(a4-6a+5)-(a4-3a+4a-6)
by expressing like term
a4-a4=0
-6a-(-3a+4a)=-5a
5-(-6)=11
:we have-5a+11
0.2,
-0.4,
-4.5
hope this helps
