What is the sum of the measures of the exterior angles of this triangle?

360

Step-by-step explanation:

112 - 51 = 61 (m∠A = 61)

180 - 61 = 119 (m∠B = 119)

180 - 51 = 129

119 + 112 + 129 = 360

x=12 units bd= 10 units

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
