Answer:
x = 47 degrees.
Step-by-step explanation:
Note that the angle x + the angle 133 are on the same straight line DPC. So they add up to 180 degrees.
Therefore x + 133 = 180
x = 180 - 133
= 47 degrees.
In words, it is: y equals g of x

Answer:
The equations that are true are
B
C
E
Step-by-step explanation:
A) States that 0 + 451 = 0, but that is not true because...
0 + 451 = 451
B) States that 130 + 210 = 210 + 130, and that is true because...
130 + 210 = 210 + 130
340 = 340
C) States that (127 + 80) + 250 = 127 + (80 + 250), and it is true because...
(127 + 80) + 250 = 127 + (80 + 250)
127 + 80 + 250 = 127 + 80 + 250
457 = 457
D) States that (123 + 57) + 180 = 153 + (87 + 180), but that is not true because...
(123 + 57) + 180 = 153 + (87 + 180)
123 + 57 + 180 = 153 + 87 + 180
360 = 420 (but this does not make sence)
E) States that 497 + 0 = 497, and it is true because...
497 + 0 = 497
497 = 497
