Answer:
514.5 ft.³
Step-by-step explanation:
Volume of a triangular prism
= base area × height
In the figure, the base is a right-angled triangle.
The base area
= (7×7)÷2
= 24.5 ft²
The volume of the prism
= 24.5×21
= <u>514.5 ft³</u>
Answer:
cos34°
sin56°
Step-by-step explanation:
Sin(2x+42)= sin90-(3x+13)
Sin(2x+42) = sin(90-13-3x)
Sin(2x+42) = sin(77-3x)
2x + 42 = 77-3x
5x. = 35
X = 7
If x = 7
cos(3x+13) = cos((3*7)+13)
cos(3x+13) = cos(21+13)
cos(3x+13)= cos34
And
sin(2x+42) = sin((2*7)+42)
sin(2x+42)= sin (14+42)
sin(2x+42) = sin56
