Answer:
∠R = 55.6°
∠Q = 62.2°
∠S = 62.2°
Step-by-step explanation:
total interior angle sum = 180°
2x + 29 + 4x + 9 + 4x + 9 = 180
combine like terms:
10x + 47 = 180
subtract 47 from both sides of the equation:
10x = 133
divide both sides by 10:
x = 13.3
∠R = 2(13.3) + 29 = 55.6°
∠Q = 4(13.3) + 9 = 62.2°
∠S = ∠Q
36
1/2x
To solve this type of fraction you need to times the inverse of the bottom fractal, both over and under. In this case the inverse of 1/2 is 2/1
F=2E
ANGLE F+ANGLE E=120
2E. + E. =120
3E=120
E=40
y= 3/2x+40
y= rise/run+ y-intercept
di ko po alam ehh
sorry po
