Answer:
1 : 3 : 5
Step-by-step explanation:
Given
$150 : $450 : $750 ( divide each part of the ratio by $150 )
= 1 : 3 : 5
Answer:
x - 9
Step-by-step explanation:
Answer:
239 degrees.
Arc is circumference so length = r * 4.17133691221
Step-by-step explanation:
We eliminate RSQ in degrees = 90 + 31 = 121
So that;
RPQ = 360 -121 = 239 degrees
2pi radius (239/360) = r6.28318530718 (0.66388888888)
= r * 4.17133691221

Let the third angle be x.
Sum of the interior angles of a triangle = 180°
42 + 84 + x = 180
126 + x = 180
x = 180 - 126
x = 54°
Hence, the third angle is 54°.
