Isn't this the wrong section to be asking in?
Anyways, though:
The man clearly saw the water vapor present in the room as he entered the sauna.
You have to use your area equations.like basex height
Is that what your looking for or no
1) Angle T = 72°
Angle U = 54°
2) Angle M = 76°
Angle N = 76°
<em>Explanation</em><em>:</em><em> </em>
<em> </em> 1. Isosceles triangle (since 2 sides are equal)
Angle U = Angle S = 54° (equal sides of a traingle have equal angles)
angle U + angle S + angle T =180 (Angle sum Property)
54° + 54° + angle T = 180°
108 + angle T = 180°
Angle T = 180 - 108
= 72°
2. Isosceles triangle again (same properties)
angle L + angle M + angle N = 180
28 + angle M + angle N = 180
angle M + angle N = 180 - 28
angle M + angle N = 152
"angle M and N will be equal since it is
isosceles triangle"
so, 2x (M&N) = 152
x = 152 ÷ 2
= 76
therefore angle M = angle N = 76°
