Answer:
Well, at least you improved. But maybe you should use another source besides brainly for your tests. Sometimes people put the wrong answers just to get points.
I hope you do better next time! Good luck!!

Answer:
63° (same as Z)
Step-by-step explanation:
The question indicates that ΔXYZ is similar to ΔEDF.
By definition, when we indicate that triangle XYZ is similar to the triangle EDF, the order of the letters is important and match the congruent angles.
So, ∠X = ∠E, ∠Y = ∠D and ∠Z = ∠F
It's hard to see because the angles are quite similar in opening (56°, 63° and 61°), and the drawing doesn't seems to be to scale.
But according to the naming convention: ∠Z = ∠F
Since ∠Z = 63°, ∠F = 63°
Answer:
Answers in step-by-step.
Step-by-step explanation:
We are going to make Sarah the variable "s."
Using the given information, the following equation is derived to calculate Sarah's distance.
And the following equation will be used to calculate what Sarah collected using "p" for pledged money.
If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.
- P=18S
- 450=18S
- 450/18=S
- 25 miles = S
Using Sarah's distance, we can calculate Semir's either the first equation.
- S=2n-5
- 25=2n-5
- 30=2n
- 15=n
- Semir walked 15 miles.
We already found Sarah's distance to be 25 miles.
Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.
His formula is the same as Sarah's, but we'll use SS for his variable.
- P=18SS
- 378 = 18SS
- 378/18=SS
- 21= SS
- SungSo walked 21 miles.
