Answers
First Picture :
First Triangle = 180 - (75 + 72) = 33
Second Triangle = 180 - {65 + (180 - 125)} = 180 - 120 = 60
Third Triangle = 180 - {180 - (90 +55)} = 180 - 35 = 145
Fourth Triangle = 180 - {180 - (62 + 62)} = 180 - 56 = 124
Second Picture :
y = 180 - (54 + 64) = 180 - 118 = 62
x = 180 - (62 + 64) = 180 - 126 = 54
x + y = 62 + 54 = 116
B is the Answer
Third Picture :
As Both are Similar Triangles Angle R = Angle Z
⇒ Angle Z = 35
Angle Y = 180 - (X + Z) = 180 - (70 + 35) = 180 - 105 = 75
So the other Two measures of Triangle XYZ are 35 and 75
Fourth Picture :
y = 180 - {98 + (180 - 134)} = 180 - 144 = 36
Option D is the Answer
Fifth Picture :
Pair of Triangles which are similar are :
Triangle - 1 : 25 and 35
Triangle - 2 : 25 and 120
Triangle - 1 : 100 and 60
Triangle - 2 : 100 and 20
Triangle - 1 : 90 and 20
Triangle - 2 : 20 and 90
