7.34 and 3 squareroot 6 simplified
X + x + x+ 21 = 180
3x = 180 - 21
3x = 159
x = 159/3
x = 53° ← the measure of <span>each of the smallest angles
53 + 21 = 74</span>° ← the measure of the largest angle
Answer:
Opposite sides of the parallelogram are equal. Here, 60°+60°+ Angle ZWX + Angle ZYX = 360°
or,2* Angle ZYX = 240° [ Angle ZWX = Angle ZYX]
So, Angle ZYX = 120°
Then, In ∆ENY;
102° + (120-84)° + Angle ENY = 180° [Sum of all angles of a triangle.]
or, 36° + Angle ENY = 78°
So, Angle ENY = 42°
