Answer:
∠ E = 56°
Step-by-step explanation:
the external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ MGF is an exterior angle of the triangle , then
10x + 12 = 5x - 4 + 76
10x + 12 = 5x + 72 ( subtract 5x from both sides )
5x + 12 = 72 ( subtract 12 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12
Then
∠ E = 5x - 4 = 5(12) - 4 = 60 - 4 = 56°
Answer: a: -2, b: 0
Step-by-step explanation:
f(2) means that x=2, and we need to solve for y.
On the graph, it has a point of (2, -2) and since it's a function that is the only possible output. Therefore, f(2)=-2.
f(x)=-4 means that y=-4, and we need to solve for x.
On the graph, the point (0,-4) exists, and since the function contains only one output, it must be correct. Therefore, x=0.
-(7+8/100)
= -(7+4/50)
= -(7+2/25)
= -177/25
Y would equal 0. 2x2=4 and 4-4=0.
Set up a ratio for this problem:
.25 in/50 miles = 2.5 in/x
.25x = 125
then divide by .25
The actual distance is: 500 miles
