Answer:
B
Step-by-step explanation:
Since the triangle is right use the sine/ tangent ratios to solve for x and y
note sin60° = and tan60° =
sin60° = =
ysin60° = 3
y × = 3
multiply both sides by 2 and divide by
y v= 6 = 6
tan60° = =
xtan60° = 3
x × = 3
divide both sides by
x = 3 = 3
Answer:
3 a : 2 b = 6 : 1
Step-by-step explanation:
<em> =
</em>
<em>3 ( a + b) = 5 ( a - b) </em>
<em>3 a + 3 b = 5 a - 5 b </em>
<em>5 b + 3 b = 5 a - 3 a </em>
<em> 8 b = 2 a </em>
<em> 2 a = 8 b</em>
<em><u>a = 4 b</u></em>
<em>3 a = 3 × 4 b</em>
<em><u>3 a = 12 b</u></em>
<em>3 a: 2 b = 12 b : 2 b</em>
<em>3 a : 2 b = 6 : 1</em>
