Answer:
1.1.1 sin(241°) = -√t
1.1.2 cos(61°) = √(1 -t)
Step-by-step explanation:
<u>Given</u>:
sin(61°) = √t
<u>Find</u>:
1.1.1 sin(241°)
1.1.2 cos(61°)
<u>Solution</u>:
1.1.1 sin(180° +x) = -sin(x)
sin(241°) = -sin(61°) = -√t
__
1.1.2 cos(x) = √(1-sin²(x))
cos(61°) = √(1 -(√t)²) = √(1 -t)
Answer:
1: $11
2: $43.19
3: $128.57
Step-by-step explanation:
10 • 1.10 = 11
39.99 • 1.08 = 43.19
43.19 • 3 = 128.57

Answer:
16 ft²
Step-by-step explanation:
The complete question is attached.
A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.
The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.
Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:
The area of a trapezoid = [(3 + 5)/2] * 4
The area of a trapezoid = 16 ft²
