Good evening
The absolute value has the following property:
Apllying:
The average temperature range is between 45 and 65 degrees.
Answer:
A ceiling fan has 13-inch blades (so the radius of the circular fan is 13 inches). Suppose the linear speed of the tip of a blade is 8 feet per second
Answer:
x=70
y= 40
Step-by-step explanation:
the triangle containing x is an isosceles triangle so two of the sides are 55.
55+55+x=180.
110+x=180
110-110+x=180-110
x=70
Triangle BAC is equilateral so 180/3=60. Now
x+60+c=180
70+60+c=180
130+c=180
130-130+c=180-130
c=50
That gives us one corner of triangle CBD. We know a second angle is 90 so
50+90+y=180
140+y=180
140-140+y=180-140
y=40
I think that is correct but you are free to check it yourself
