In rectangle SORE below, m∠REO = (x + 50)° and m∠SEO = (3x - 20)°, what is the measure of m∠RSE?

65degrees

Step-by-step explanation:

In rectangle SORE below, m∠REO = (x + 50)° and m∠SEO = (3x - 20)°, what is the measure of m∠RSE?

From the rectangle SORE, m<SEO + m<RSE = 90

Substitute the given angles

x+50+3x-20 = 90

4x + 30 = 90

4x = 90-30

4x = 60

x = 60/4

x = 15

Get m<RSE

mRSE = m<REO = x+50

m<RSE = 15+50 = 65degrees
