Answer: fifty four degrees (54)
Step-by-step explanation: Using the law of sines you'd multiply both sides by b then plug in the known values... sin(B)= 9/11xsin(80degrees). Then, you'd evaluate to find B and after solving you'd reach 54
Part 1) The equation of a circle is (x+4)²+(y−5)²<span>=121.
What is the center and radius of the circle?
we know that
the equation of a circle is of the form
(x-h)</span>²+(y-k)²=r²
in the problem
(x+4)²+(y−5)²=121.------> (x+4)²+(y−5)²=11²
the center (h,k) is the point (-4,5) and the radius is 11
Part 2) we have that
(x+15)²+(y−12)²=25-------> (x+15)²+(y−12)²=5²
we know that
<span>the greatest distance, in feet, a person could be from the lamp and be detected is the radius
</span>
the radius is equal to 5 ft
the answer Part 2) is 5 ft
Part 3) we have that
(x−9)²+(y+11)²=16--------> (x−9)²+(y+11)²=4²
the radius is equal to 4 m
so the diameter is ------> 4*2-----> 8 m
the answer Part 3) is
8 m

Answer: 7 girls, because 11(7)+7(10)+147
Step-by-step explanation: hope this helps
can i have brainliest and a thx please
[ a⁵ (a²b³)⁵ ] / [ a²b⁻² ]
[ a⁵ (a¹⁰b¹⁵) ] / [ a²b⁻² ]
[ a⁵⁰ b⁷⁵ ] / [ a²b⁻² ]
I think this: a⁴⁸b⁷⁷ is the answer.
Hope this helps :)
