You get scores of 85 and 91 on two history test.Wright and solve an inequality to find the scores you can get on your next histo

Goryan [66]

Let x = score on next test
(85+91+x)/3 $\geq$ 90
x $\geq$ 94

Help! Geometry Triangle Congruence

Feliz [49]

Answer:

Step-by-step explanation:

Thank your for revising and improving the image.

Assuming DF is a straight line,

Given E is the mid-point of DF

mCE = mGF

CE || GF

Then

mDE = mEF (E midpoint of DF)

Angle DEC = Angle EFG (corresponding angle, DF transversal of parallel lines CE and GF)

mCE = mGF (given)

Then triangles DCE and EGF are congruent by reason SAS (side-angle-side)

Please help the first two answers aren’t right.

Airida [17]

It has to have an average of 10 feet per minute for 5 minutes, which means in five minutes the total of feet would have to be 50.
So you would add all these numbers up and you would get 38.
50 - 38 = 12 so the answer is 12ft
