Answer:
x = 81, y = 68 and z = 99
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle, thus
z = 63 + 36 = 99
x and z form a straight angle and are supplementary, so
x + z = 180, that is
x + 99 = 180 ( subtract 99 from both sides )
x = 81
The sum of the 3 angles in a triangle = 180°, thus
z + y + 13 = 180, that is
99 + y + 13 = 180
112 + y = 180 ( subtract 112 from both sides )
y = 68
Answer:
m = -4.33333 or -4 and 1/3
Step-by-step explanation:
gradient = (difference in y)/(difference in X)
m = (-1-12)/(8-5)
m = -13/3
m = -4.3333333

Answer:
Option A. 0.4 of an orange
Step-by-step explanation:
Formula to calculate the opportunity cost is
Opportunity cost = 
In this question for the high yield, sacrificed thing is 100 tubs of grapes and gain is to produce 250 tubs oranges.
Opportunity cost = 
of an orange
Therefore, Option A. 0.4 of an orange, will be the answer.
