help with this math question please?

you can help me with one or both. thank you.

the measures of two consecutive angles of a parallelogram are in the ratio 3:7. find the measure of an acute angle of the parallelogram.

this one is science.

a student performed an experiment to determine if treating 500 tomato plants with an auxin will make them grow faster. these results are shown below.

day 1- 10 cm

day 5- 13 cm

day 10- 19 cm

day 15- 26 cm

day 20- 32 cm

day 25- 40 cm

explain why the student can not draw a valid conclusion from these results.

answer to your science question is that the student did not leave any of the tomato plants untreated, therefore does not have a “control” to compare results to. (i think)

answer to the maths question is 54 degrees. (i think) i’ll let you do the working

the acute angle x would be 180-(x+y) y being the other angle for example if y was 100 then x would be 80 but this is not the correct ratio so about say x is 50 y is120 is closer use a calulator to get exact using 3x+7x=180 this is becuse the angles in a paralleigram equl 360 and say the two on the bottom or top they equal 180 degrees jay has a good idea 3/7 is 1.43…..use calc and his method to get exact to as many decimals as u want

Math question:

the acute angle equals 54

if the acute angle is 3/7 the size of the obtuse angle which is equal to 1/1 the total measure for both angles is 1.43 (1+.43). Next you divide 180 (the sum of the two consecutive angles) by 1.43 which gives you 126 (the obtuse angle). 180- 126=54. Sorry that might sound a bit complicated.
