Answer:
B
Step-by-step explanation:
∠ 2 and 37° are vertically opposite angles and are congruent, then
∠ 2 = 37°
∠ 1 and 37° are a linear pair and sum to 180° , that is
∠ 1 + 37° = 180° ( subtract 37° from both sides )
∠ 1 = 143°
∠ 1 and ∠ 3 are vertically opposite angles and are congruent , then
∠ 3 = 143°

Answer:
60 boys
Step-by-step explanation:
boys : girls = 3 : 5
Total number of people = 160
Let y = common factor:
Therefore, 3y + 5y = 160
⇒ 8y = 160
⇒ y = 160 ÷ 8 = 20
Boys = 3y = 3 x 20 = 60
Girls = 5y = 5 x 20 = 100
So there are 60 boys and 100 girls
<em>Answer: i=9</em>
<em />
<em>Step-by-step explanation:</em>
<em>-16=-4(-5+i)</em>
<em>-16=20-4i</em>
<em>-20 -20</em>
<em>-36=-4i</em>
<em>Divide by -4 </em>
<em>i=9</em>
