Answer:
450
Step-by-step explanation:
639 is what percent of 142? = 450.
Answer:
60
Step-by-step explanation:
1, Extand line y for which y intercepts CB at point K
2, line y is a straight line and thus KAB=180-110=70
3, AY parallel to CX thus angle CKA=130 which is a alternative angle of BCX (if you can't see then try to extend CX as well
4,BKA=180-130=50 as BC is a straight line
5, the sum of interior angle of a triangle is 180, and we have KAB and BKA, thus angle ABC = 180-KAB-BKA=180-70-50=60
Answer:
106°
Step-by-step explanation:
Supplementary angles total 180°, so the one supplementary to 74° is ...
180° -74° = 106°
