Answer:
yes, SAS
Step-by-step explanation:
Two sides are given, either side of a vertical angle. So, the angles are the same. If the sides are proportional, the similarity will be by SAS (two sides, either side of an angle).
The ratios of short to long sides are ...
39/52 = (3·13)/(4·13) = 3/4
63/84 = (3·21)/(4·21) = 3/4
The sides are proportional and the angle between them is congruent, so ...
the triangles are similar by SAS.
Answer:
Actual distance between two city = 40 miles
Step-by-step explanation:
Given sample size;
1 inch = 10 miles
Distance between two city = 4 inch
Find:
Actual distance between two city
Computation:
Actual distance between two city = Sample size of 1 inch in miles x Distance between two city
Actual distance between two city = 4 x 10
Actual distance between two city = 40 miles
We know that
circumference C=2*pi*r
for r=4 ft
C=2*pi*4-----> 25.12 ft
by proportion
25.12/360°=L/60°---------> L=60°*25.12/360°-----> L=4.19 ft
the answer is
4.19 ft
