If O is 31 degrees and T is 121 degrees then what is the measure of angle A?
Insufficient data. If O, T and A are angles of a triangle,
then
O + T + A = 180º
To find the measure of angle A, we need more information about the triangle. Specifically, we need to know the relationship between the angles O, T, and A.
In a triangle, the sum of all three angles is always 180 degrees. Hence, we can set up an equation using the given information:
O + T + A = 180 degrees
Substituting the given values:
31 + 121 + A = 180
Now, to solve for A, we can isolate it by moving the other terms to the other side:
A = 180 - 31 - 121
A = 28 degrees
Therefore, the measure of angle A is 28 degrees.
