If it were a complete circle, its circumference would be

             (π) x (diameter) = (π) x (2R)  =  70 π inches .

Since it's only half of the circle, the length of the curved part is

                              70 π / 2  = 35 π  =  <em>109.9 inches</em> .

What is the first step to solve the following system of equations using substitution? 3x+y=15 5x-3y=11Divide the second equation
Nina [5.8K]

Answer:

(4, 3)

Step-by-step explanation:

#1. Isolate x:

3x + y = 15

y = 15 - 3x

Substitute and solve for x:

5x - 3y = 11

5x - 3(15 - 3x) = 11

5x - 45 + 9x = 11

5x + 9x = 11 + 45

14x = 56

x = 4

Substitute and solve for y:

y = 15 - 3x

y = 15 - 3(4)

y = 15 - 12

y = 3

For this case, we can model the problem as a rectangle triangle.
 We know:
 Height of the triangle.
 Base of the triangle.
 We want to know, angle between the hypotenuse and the base of the triangle.
 For this, we use the following trigonometric relationship:
 tan \alpha =  \frac{7.4}{9.3}
 Clearing the angle we have:
 \alpha = arctan(\frac{7.4}{9.3} )
 \alpha = 39
 Answer:
 
the angle of depression from the spotlight to the bottom of the door is:
 
A) 39 degrees
