Answer:
45 is the answer
Step-by-step explanation:
first you have to know the sum of interior angle of that pentagon (540)
then add the all angle.
148 + x + 112 + 90 + 3x + 10 = 540.
or, 360 + 4x = 540
or, 4x = 540 - 360
or, 4x = 180
or, x = 180/4
or, x = 45

Answer:
y<7 since if you subtract 1 from both sides and then divide both sides by 5 you get y<7

Divide both the numerator and denominator by 9 to get;

Convert the improper fraction to a mixed number;
X= y(d-b) over a-c would be the answer
