Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
= = ( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13
To find the percent of error divide how off the wrong answer was by the right number, then multiply by 100.
Bryan's guess of 730 was 120 less than the actual number so you would divide 120 by 850. 120/850 = 0.141
Then we would multiply that by 100. 0.141 * 100 = 14.1
His percent of error was 14.1%. The percent of error is negative since his guess was less than the right answer.
76.2cm : 30in is the answer I think
Answer:
June, Mitchell and Nick are the ones who drew the line of symmetry correctly because if you were to cut that in half, both sides remain the same shape and size. Stephanie, Liz, and Brandon are wrong because if you cut that you get different shapes and sizes, they will not be identical.
