Using trigonometry
tan(x)=9/6
use your calculator to find x using tan-1(9/6) and you get 56.3° which is basically the first answer
Answer:
42
Step-by-step explanation:
The whole thing is 360 degrees. To me, it looks like the angles in the middle are divided in to 4 equal parts. 360/4=90. Now set the equation equal to 90. 90-6=84, and 84/2=42.
Answer:
f(1) = -4
Step-by-step explanation:
Given that,
f(x) = 2x-6
We need to find the value of f(1).
Put x = 1 in the above expression.
f(1) = 2(1)-6
= 2-6
= -4
So, the value of f(1) is equal to -4.
Answer:
a person can work out 50% of the maximum (50% of 194 is 97) and 85% of the maximum (85% of 194 is 164.9). This means that the target heart rate for a 20-year-old is approximately 97–165 bpm.
Step-by-step explanation:
so I'd say 21
Answer:
The width of the art projects of area 63.6 square inches is 7.97 inches .
Step-by-step explanation:
Given as :
The area of the square art project = 63.6 square inches
Since The shape of the art project is square
So, The Area of square = A = side × side = side²
Now, let the measure of the width of art project = w inches
I.e side = w inches
or , A = side²
Or , A = w²
Or, 63.6 = w²
So, w = 
I.e w = 7.97 inches
So, the width of the projects = w = 7.97 inches
Hence The width of the art projects of area 63.6 square inches is 7.97 inches . Answer
