Answer:

44°

Step-by-step explanation:

First, m ∠ D=112° and ∠ABC are congruent in a parallelogram and congruent angles have same measure so m ∠ ABC=112° as well

Second, ∠ABC and ∠CBE are supplementary angels so they add up to 180° because adjacent angles that form a line are suplementary, therefore, ∠CBE=180-112=68°

Third, ∠CBE≅∠BCE because the ΔCEB is isosceles since is given CE≅BE and base angles of isosceles triangles are congruent.

Congruent ∠s have same measure so m∠BCE =68° as well

Last sum of angles in a Δ is 180° so from ΔCEB we have

m ∠E = 180-68-68=44°

Answer:

8 weeks

Step-by-step explanation:

Since we know that the sunflower in Class B has a rate of 1/4 less, we know that it will eventually catch on to sunflower A.

First, we have to look at the difference which is 2. How many 1/4ths makes 2?

Therefore, 8 weeks would be your answer.

Answer:

( Hint)

To find the curve of best fit, you will need to do exponential regression. Press STAT, then right arrow to highlight CALC, and then press 0:ExpReg . The correlation coefficient is r, which is 0.994 in this case. That means that the equation is a 99.4% match to the data.

What is the measure of ∠DBA?

Arisa [49]

Answer:

Step-by-step explanation:

90/5 because CBE is 90 so CBA would be 90 too.

90/5 is 18 so do 2 times 18.

x=18

2(18)=36
