A triangle has angle measurements of 46° and 103°. What is the measurement of the third angle?

31°.

Step-by-step explanation: All interior angles for a triangle should add up to 180°.

46° + 103° = 149°

To make 180°, we have to add another 31°, which is the third angle measurement. This is for the interior angles of a triangle.

Have a great day! :)

31°

Step-by-step explanation:

In every triangle, the result of all three angles together has to be 180°.

So, 46+103= 149

180-149 = 31

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
