2y + 3y + 4y = 9y
180 divided by 9 = 20
Y = 20 degrees
Its the letter G because 17.64 divided by 7 is 2.52
2a + c = 1850
2a + c (-c) = 1850 (-c)
2a = 1850 - c
2a/2 = (1850 - c)/2
a = 925 - (c/2)
hope this helps
The reciprocal of a fraction is just that fraction flipped.
So the reciprocal of 1/12 would be 12/1.
Applying the angle addition postulate, the measure of angle ROS is: 16°
<h3>How to Apply the Angle Addition Postulate?</h3>
Given the following angle measures:
m<QOS = 49°
m<POR = 56°
m<POQ = 23°
Find the measure of angle QOR:
m<QOR = m<POR - m<POQ [angle addition postulate]
Substitute the values into the equation
m<QOR = 56 - 23
m<QOR = 33°
Find the measure of angle ROS:
m<ROS = m<QOS - m<QOR [angle addition postulate]
Substitute the values into the equation
m<ROS = 49 - 33
m<ROS = 16°
Therefore, applying the angle addition postulate, the measure of angle ROS is: 16°
