15x+25=20x
Isolate x. Subtract 15x from both sides.
25= 5x
Now divide both sides by 5 to find the value of 1x.
5=x
Final answer: x=5
SOH CAH TOA tells you the sine ratio is
Sin = Opposite/Hypotenuse
sin(x) = 12.5/15
Then the angle x can be found using the inverse function.
x = arcsin(12.5/15) ≈ 56°
The appropriate choice is
b) 56
Answer:
r = 3.5 ft
Step-by-step explanation:
The circumference of a circle is the distance around the circle. The seat accommodates 11 people . Each person has 2 ft of space along the edge of the table .
Therefore ,
circumference = 11 × 2 = 22 ft
circumference = 2πr
where
r = radius
circumference = 2πr
22 = 2 × 22/7 × r
22 = 44r/7
multiply both sides by 7/44
r = 22 × 7/44
r = 7/2
r = 3.5 ft
