Answer:
Step-by-step explanation:
2/5 is 0.4
0.75 is 3/4
5/8 is 0.625
0.875 is 7/8
2/5=0.4
0.75=3/4
5/8=0.625
0.875=7/8
The angle supplementary to the angle 39° Mabel measured is C. 129°.
When the sum of the two angles is 180° they are said to be supplementary.
When the sum of the two angles is 90° they are said to be complementary.
Given, Mabel measured an angle on her math worksheet with her protractor. The angle measured 39°.
Therefore, The angle supplementary to the angle she measured is,
= (180 - 39)°.
= 129°, As the sum if the sum of two angles are supplementary their sum is
180°.
