Answer:
?=91 degrees.
Step-by-step explanation:
There is no x- I'll find ? though.
So, angles in a triangle must equal 180.
180-29-62=89. The last angle in the triangle is 89 degrees.
A straight angle is equal to 180 degrees. ? + 89=180.
180-89=91.
?=91 degrees.
Hope this helped!
In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.
But in the second one, the summation only applies to the 2n , so

The difference between five 3s the first time and one 3 the second time
is your 12 .
