Answer:

angle edf is 70

Step-by-step explanation:

triangle angles always add up to 180. So if you have 40 degrees at angle e already, 180-40 = 140

since side DE and side EF are congruent, that means its an isosceles triangle. One rule for that type a triangle is that the two base angles are equal. So you can just do 140/2 = 70

hope that helps!

The triangles below are similar. Which similarity statements describe the relationship between the two triangles? Check all that

Gekata [30.6K]

<u>Complete Question</u>

In triangle ABC: AC=10 , AB=5., Angle C = 30 degrees.

In Triangle DEF: ED= 7.5 , DF=15, Angle F =30 degrees , Angle E = 90 degrees.

Answer:

A, D and E

Step-by-step explanation:

The diagram is drawn and attached below.

Triangle ABC is similar to Triangle DEF. (Option E)

Writing it backwards:

Triangle CBA is similar to Triangle FED. (Option A)

Also,

Triangle BAC is similar to EDF. (Option D).

Therefore, A, D and E are the similarity statements that describe the relationship between the two triangles.

Describe how you can use the information in a table showing a linear relationship to find the slope and y-intercept for the equa

marshall27 [118]

The slope from a table can be found by finding what number keeps adding on new points. (horrible wording sorry)
EXAMPLE:
x y
0 2
1 4
2 6
3 8
4 10
for the X values it keeps adding by 1 and the Y values keep adding by 2. Since the slope is the change in y over x the slope would be 2/1 therefore simplifying to a slope of 2. To find the y intercept, you have to look for a value in which the X value is 0. From the table, this would be 2 so the y int is (0,2)
