The value of sin(30°) is: One-half ⇒ 2nd answer
Step-by-step explanation:
In a right triangle there are two acute angles, the side opposite to the right angle is called hypotenuse, and the other two sides are opposite and adjacent to the acute angles
- sine the acute angle (sin) = opposite side to it/hypotenuse
- cosine the acute angle (cos) = adjacent side to it/hypotenuse
- Tangent the acute angle (tan) = opposite side to it/adjacent side to it
In Δ QRS:
∵ m∠QRS = 90°
∵ SQ is opposite to ∠QRS
∴ SQ is the hypotenuse
∵ SQ = 10 units
∴ The hypotenuse = 10
∵ m∠RSQ = 30°
- The opposite side to ∠RSQ is RQ
∵ RQ = 5 units
∴ The opposite side to the angle of 30° = 5
∵ sin(30°) = opposite side to 30°/hypotenuse
∵ The opposite side to angle 30° = 5
∵ The hypotenuse = 10
∴ sin(30°) = 
∴ sin(30°) = 
The value of sin(30°) is: One-half

Answer: 30 % Off
Step-by-step explanation:
Question 1
Total budget = 180 + 475 + 15 + 50 + 65 + 25 + 150 + 30 = $990
Real spending = 182 + 475 + 12 + 65 + 68 + 12.50 + 150 + 36 = $1000.5
Mae Green didn't stay within the allocated budget

Question 2
Eleanor:
Income = 380.48
Spending = 16.50
Peter:
Income = 120 + 13.65 + 100 = 233.65
Total income = 233.65 + 380.48 - 16.50 = 597.63
-------------------------------------------------------------------------------------------------------------
Question 3
Total spent = 540 + 48.55 + 34.15 + 12.80 + 18.95 + 38.60 + 2 + 6.50 = 701.55
-------------------------------------------------------------------------------------------------------------
Question 4
Marie's new balance = 250.65 - [21.95+48.50+75.60] + 55 = $159.50
------------------------------------------------------------------------------------------------------------
Question 5
[235/825] × 100 = 28.48%
