Find the measure of angle x in the figure below:
A:35°
B:47°
C:73°
D:78°

Step-by-step explanation:
[tex]56 + 51 + y = 180 \\ y = 180 - 107 \\ y = 73[/tex]
[tex]y + x + 72 = 180 \\ 73 + 72 + x = 180 \\ x = 180 - 145 \\ x = 35[/tex]
Hope it helps
A straight angle is an angle equal to 180 degrees
Solve for y
y + 51° + 56° = 180°
y = 180° - 56° - 51°
y = 73°
Total interior angle of a triangle sum ups to 180°
Solve for x
y + x + 72° = 180°
73° + x+ 72° = 180°
x = 180° - 72° - 73°
x = 35°
