Answer:
angle A is 75:the four corners are 90 degrees so 75+15 is 90 and is looks like A is the same.
angle C is 55:180-125=55
Angle D is 90-15 so think its 75?

Step-by-step explanation:
Given d = - 3 and a₄ = 17
To obtain terms before a₄ , then do the opposite and add 3 , that is
a₃ = a₄ + 3 = 17 + 3 = 20
a₂ = a₃ + 3 = 20 + 3 = 23
a₁ = a₂ + 3 = 23 + 3 = 26
Then arithmetic sequence is
26, 23, 20, 17, ...........
World population distribution is uneven because of the different measures of the factors affecting population, such as life expectancy, economic development etc
Answer:
(19.88 + 20.12) /2 = 20 middle of range
can be + or - .12 from there
| w - 20 | = distance from middle
so
| w - 20 | < .12
