Step-by-step explanation:
for nr. 1
sum of angles in a triangle=180
x=180-(81+84)=15
acute triangle
for nr.2

obtuse triangle
If each ticket is $9.75, then you multiply $9.75 by how many tickets he's buying. In this case he's buying 3, so it's 9.75x3. The total for that is $29.25. You subtract $28.25 from $43 and that leaves him with $13.75
<span>The coterminal angles of angle A are given by adding k times 360° to it, where k is an integer, positive or negative.
Similarly, all angles that are coterminal with 141° are given by
141° + k * 360° where k is a positive or negative integer.
That is 141° + 360°, 141 + 2*360° , 141+3*360° and so on
and 141° - 360°, 141° -2*360°, 141° - 3*360° and so on.
