If 2 inches equals 40 miles, then 1 inch equals 20 miles.
115 miles/20 miles=5.75
The cities would be 5.75 miles apart on the map.
Answer:
a=21
b=69
c=42
d=138
Step-by-step explanation:
c is supplementary to d (which is 138), so c=180-138= 42.
angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.
angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.
Answer:
Choice A x= 16, y= 9√2
Step-by-step explanation:
x= 9+7 =16
y= √9²*2= 9√2
