Answer:
18 nickels, 9 dimes, and 6 quarters.
Step-by-step explanation:
Just use the guessing method. I started with 15 and then went to 18. and got it right. A nickel a worth five cents so 18 times 5 = 90 cents. 18/3 is 6 and 18+6=24. 24/2 is 12 and 12-3 is 9. A dime is worth 10 cents so 9 times 10= 90 cents. A quarter is worth 25 cents and 6 times 25=150. 150+90+90+330 If you get this right can i please have brainliest
138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42
19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29
