Step-by-step explanation:
I'm pretty sure
Answer:
x = 12, z = 86
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180 degrees.
(12x -58 + 13x - 62 ) = 180°
12 x + 13x -58 - 62 = 180°
25x - 120 = 180
25x = 180 + 120
x = 300/ 25
x = 12
----------------------------------------------------------------------------------
(z° + 13x - 62) = 180
(z° + 13(12) - 62 )= 180
(z° + 156 - 62 )= 180
(z° + 94 ) = 180
z° = 180 - 94
z = 86
It matters what D is.
the way to do it is like 8 to the third power th math is:
8 times 8=64
8 times 64=512
8 times 512=4096
3 times
