Answer:
x = 9 & y = 29
Step-by-step explanation:
Since we know that 7x is next to 117, that area will be equal to 180*,
7x + 117 = 180
7x = 180-117
7x=63
x=9
to find y, you can use the same method, just by finding the other angle inside. 53+7(9) + z = 180
53+63 = 180
116+z = 180
z = 180-116
z = 64.
Then we do
4y + 64 = 180
4y = 180-64
4y=116
y = 29
