Angle QPS is an inscribed angle.  Arc QS is the intercepted arc of that angle.  The rule is that the intercepted arc is twice its angle measure.  P measures 20 degrees, so arc QS measures 40 degrees.  It just so happens that angle QTS is ALSO an inscribed angle intercepting arc QS.  So angle QTS measures the same as angle P, 20 degrees.  That's a.  For b., we already stated the rule and figured out that minor arc QS is 40 degrees.  For c., major arc QTS is 360 (the measure around the outside of a circle...EVERY circle in the world) minus the minor arc of 40.  So major arc QTS measures 360 - 40 which is 320 degrees.  There you go!

the sides of a triangular birdcage are consecutive intergers if tge perimeter is 114 cm what is tge length of each side
alexandr402 [8]
Let:
x = first consecutive integer (or first side of △)
x + 1 = second consecutive integer (or second side of △)
x + 2 = third consecutive integer (or third side of △)

The formula for a perimeter of △ is simply the addition of three sides (or length). Since the given perimeter is 114 cm,
x + x+1 + x+2 = 114
3x + 3 = 114
3x = 114 - 3
3x = 111
x = 111 /3 = 37 cm
The three sides are 37 cm, 38 cm, and 39 cm.

mote1985 [20]

Answer:

$55.20

Step-by-step explanation:

Create a proportion where x is the cost of 12 lbs of walnuts:

\frac{3.45}{0.75} = \frac{x}{12}

Cross multiply and solve for x:

0.75x = 41.4

x = 55.2

So, for 12 lbs of walnuts, it will cost $55.20
