To find the measure of the third angle in a triangle, we use the fact that the sum of the angles in a triangle is always 180°.
Given:
1st angle = 146°
2nd angle = 7°
Now, we can calculate the third angle as follows:
Third angle = 180° – (1st angle + 2nd angle)
Third angle = 180° – (146° + 7°)
Third angle = 180° – 153°
Third angle = 27°
It looks like my answer doesn’t match any of the options provided. Please double-check the angle measurements or have a look at the options again! If you’d like more help, feel free to ask!
To find the measure of the third angle in a triangle, you can use the fact that the sum of the angles in a triangle is always 180°.
1. Start by adding the measures of the two known angles:
( 146° + 7° = 153° )
2. Then, subtract this sum from 180° to find the third angle:
( 180° – 153° = 27° )
It seems there might be an error as 27° is not among the provided options (0°, 30°, 47°, 37°). Therefore, it would be helpful to double-check the angles given in your question.
