Answer:
8.2
Step-by-step explanation:
sin^-1 (8.2/21) is 22.984 which is pretty close to 23
Answer:
24.0 square feet
Step-by-step explanation:
The area of the sector is given by ...
A = (1/2)r²θ . . . . . where θ is the angle in radians
The area of the circle is the same, with θ=2π, so is ...
A = πr²
__
In this problem, the area of the sector is ...
A = (1/2)(9 ft)²(24π/180) = 27π/5 ft² ≈ 16.9646 ft²
The area of the circle is ...
A = π(1.5 ft)² = 9π/4 ft² ≈ 7.0686 ft²
Then the total area of the exclamation point is ...
16.9646 +7.0686 ≈ 24.0 . . . ft²
The area is about 24.0 square feet.
Answer: D
Two sides are equal all angles smaller than. Right angle makes them acute

Consider this option:
way_1: using points (1;10) and (-3;2) it is possible to make up the equation of the line. It is y=2x+8. Then using the form 'y=2x+8' it is possible to compare and find the answers needed: C; D.
way_2. using points of interception (-4;0) and (0;8) it is possible to substitute into every answer (if the left part = the right part, then this answer is correct, otherwise not correct). Answer: C; D,
way_3: using points (1;10) and (-3;2) it is possible to substitute into every answer (if the left part = the right part, then this answer is correct). Answer: C; D.
answer: C and D.
