Answer:
A. 3/2
Step-by-step explanation:
To find the lenght of the side opposing the 30° angle, you need to use trigonometry, since it's a right-angled triangle. You have your 30° angle and you have the side beside : therefore, you can use the sine :
sin(30) x 3 = ?
0,5 x 3 = ?
1,5 = ?
1,5 = 3/2
The worth of the bond is $307.50.
<h3>What is the worth of the bond?</h3>
The worth of the bond is the sum of the bond when it was bought and the interest earned on the bond.
Worth of the bond = interest rate + value when the bond was bought
Interest = 105% x $150
1.05 x $150 = $157.70
Worth of the bond = $157.70 + $150 = $307.50

(x-2):5=7:9
9x-18=35
9x=35+18
9x=53
x=53/9
Answer:
x = 9 and ∠ B = 40°
Step-by-step explanation:
See the diagram given with the question first.
Here we have ∠ A = ∠ B {They are corresponding angles}
Now, it is given that ∠ A = 5x - 5 and ∠ B = 3x + 13
Hence, 5x - 5 = 3x + 13
⇒ 2x = 18
⇒ x = 9
Therefore, ∠ B = 3x + 13 = 3(9) + 13 = 40° (Answer)
