Answer:

7-8.) x= 65° (right angle is always equal to 90°. subtract mo lang yung given sa 90)

9-10.) 80° ( nakalimutan ko yung tawag dito pero 180° talaga yung measurement nya. 180°inus the given.) kaso 2x pala yan. di ko lang sure kung dapat x=40 psra magkaron ka ng 2(40)=80°. sure akong 80° yan dapat.

7-8. x=65°

9-10. x=40°

Step-by-step explanation:

7.8 it is a complementary angle which is always equal to 90°

65+x=90

x=90-25

x=65

9.10. it is a supplementary angle, always equal to 180°

100+2x=180

2x=180-100

2x=80

divide both side by 2

x=40
