Answer:
120º
Step-by-step explanation:
angles of an equilateral triangle are equal so..
180 ÷ 3 = 60º
to get the exterior m⦣C
180 - interior m⦣C = exterior m⦣C
180º - 60º = 120º

Look on the graph
When x = -4, (-4, 1)
The solution is g(-4) = 1
P=44.6
P=a+b+√a^2+b^2=11+15+√11^2+15^2≈44.6
12.5 * .25=3 1/8 miles running part
3.125 * .5=1 9/16 miles kayaking part
12.5+3.125+1.5625=17 3/16 miles total race
