two angles of a triangle measure 12 degrees and 40 degrees. what is the meaure of the third angle of he triangle

The measure of the third angle of the triangle using the sum of interior angles of a triangle theorem would be 128°

Recall :

The sum of the internal angles of a triangle adds up to 180°

Hence,

Let :

Then, we'll have ;

12° + 40° + C = 180°

52° + C = 180°

C = 180° - 52°

C = 128°

Hence, the measure of the third angle is 128°

Step-by-step explanation:

Given

Angle 1 = 12

Angle 2 = 40

Required

Determine the third angle

The angles of a triangle is such that;

Substitute values for Angle 1 and 2

Subtract 52 from both sides

Hence, the measure of the third angle is 128 degrees

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
