Answer:
5√3
Step-by-step explanation:
tan30= 5/z
1/√3= 5/z
z= 5√3
The best approximation for sqrt 55 would be: B) 7 2/5
Answer:
B
Step-by-step explanation
Car A started 10 miles east of Johnstown based on the fact he traveled 90 miles in 2 hours but was 100 away from Johnstown
Car B started 20 miles away, so that mean Car B was 10 more miles east than Car A when they started.
If the points B , C and D all lie on the line segment AE then AE = AB + CD + DE
To prove the similarity between the two circles we must translate circle A by <- 1, 1> and dilate the figure by a factor of 2.
<h3>How to prove that two circles are similar</h3>
Herein we must prove that two circles are similar by taking advantage of two key characteristics: (i) Center, (ii) Radius. Based on such facts, we must apply the following <em>rigid</em> transformation:
- Translating the circle from A to B.
- Enlarging the circle A by a <em>dilation</em> factor.
Step 1 - Traslating the circle from A to B: Translation vector - (- 1, 1).
(x, y) = (2, 3) + (- 1, 1)
(x, y) = (1, 4)
Step 2 - Dilate the circle by a factor of 2.
r = 2 · 5
r = 10
