1)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
116°

Answer: 61o


SOLUTION 1 :

Step 1: 360o - 116o = 244o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 244o
Step 4: 1 unit (∠ x) = 244 ÷ 4 =  61o



2)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
120°

Answer: 60o


SOLUTION 1 :

Step 1: 360o - 120o = 240o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 240o
Step 4: 1 unit (∠ x) = 240 ÷ 4 =  60o



3)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
112°

Answer: 62o


SOLUTION 1 :

Step 1: 360o - 112o = 248o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 248o
Step 4: 1 unit (∠ x) = 248 ÷ 4 =  62o



4)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
124°

Answer: 59o


SOLUTION 1 :

Step 1: 360o - 124o = 236o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 236o
Step 4: 1 unit (∠ x) = 236 ÷ 4 =  59o



5)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
128°

Answer: 58o


SOLUTION 1 :

Step 1: 360o - 128o = 232o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 232o
Step 4: 1 unit (∠ x) = 232 ÷ 4 =  58o



6)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
104°

Answer: 64o


SOLUTION 1 :

Step 1: 360o - 104o = 256o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 256o
Step 4: 1 unit (∠ x) = 256 ÷ 4 =  64o



7)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
140°

Answer: 55o


SOLUTION 1 :

Step 1: 360o - 140o = 220o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 220o
Step 4: 1 unit (∠ x) = 220 ÷ 4 =  55o



8)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
136°

Answer: 56o


SOLUTION 1 :

Step 1: 360o - 136o = 224o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 224o
Step 4: 1 unit (∠ x) = 224 ÷ 4 =  56o



9)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
132°

Answer: 57o


SOLUTION 1 :

Step 1: 360o - 132o = 228o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 228o
Step 4: 1 unit (∠ x) = 228 ÷ 4 =  57o



10)  

Given that ∠y is thrice the size of ∠x, find ∠x.

y
x
108°

Answer: 63o


SOLUTION 1 :

Step 1: 360o - 108o = 252o
Step 2: 3 units + 1 unit = 4 units

Step 3: 4 units = 252o
Step 4: 1 unit (∠ x) = 252 ÷ 4 =  63o
