Answer:
65degrees
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
