A= 80
b= 100
c= 100
a is the same as the 80° already shown and to get b you have to subtract 80 from 180
Answer:
Option C is correct.
Step-by-step explanation:
Distance already traveled by Ed 
miles
Also, Ed is driving at a rate of 63 miles per hour.
Distance 
Speed × Time
Distance traveled by Ed in 
hours 
Total distance traveled by Ed 
Also, total distance traveled by Ed is 
miles.
Therefore,
Option C is correct.
Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)
F(x)=5x+10
5x=-10
x=-10/5
x=-2
Result is f(-2).
