11. to find <DAC a triangle will equal to 180° so subtract 100 and 32 from 180° which will give you 48.
12. is 145° not 35° because you add the two angles your given and and subtract from 180° a triangle will ALWAYS equal to 180°
13. To find <BAC a triangle will equal to 180° so subtract 88 and 57 from 180 which will give you 145°
14. is actually the same answers as 11 cause the the angle you need to find will always be the middle number which is the vertex. they both have the same vertex which is <A
15. will be the same as 11 as well.
16. <P will equal to 49.5
17 and 18. <B will actually be 90° if you see that square symbol it actually indicates it's a 90 degree angle. <A will be 48° and to find <C you add all the angles and subtract it by 180 which will give you 42°
hope this helps I'm taking geometry as well keeps practicing and this will get so easy. if you find any mistakes comment ❣
Answer: e. An experiment imposes treatments on the subjects, but an observational study does not.
Step-by-step explanation:
Experiment is scientific procedure that is undertaken by an individual or a researcher in order for the person to either make a discovery, or test a hypothesis.
Observational studies are the studies whereby the researchers just observe the impact of a treatment or risk factor e.g. cohort studies. In observational study, the researchers just collect data based on what they've either heard or seen and they've no control over such variables collected whole for an experiment, treatments are applied to a group and the effects are recorded.
Use long subtraction to evaluate.

Answer:
(f+g) (x)= -5x-4= (-3x-2)
or, -5x + 3x= -4+2
or, -2x= -2
or,x= 2/2
:. x= 1
Step-by-step explanation:
