Answer:
Step-by-step explanation:
The supplement of the exterior angle is 180 - 75 = 105
In a cyclic quadrilateral (a four sides figure where all the vertices touch the circumference of a circle), the opposite angles are supplementary. Therefore <a = 180 - 105 = 75
But I think you already knew that.
2 + n = 7/8n - 15
2 + n - 7/8n = 7/8n - 7/8n - 15
2 + 1/8n = - 15
2 - 2 + 1/8n = - 15 - 2
1/8n = - 17
n = - 136

X - the number of plants in 8 in pots
y - the number of plants in 10 in pots

4 plants in 8 in pots and 2 in 10 in pots.
Answer:
2
Step-by-step explanation:
u = 1+i
v = 1-i
u+v = 1+i + 1-i
= 1+1+i-i
= 2
