It's a similar triangle so the ratios of corresponding sides should be equal which means

BC/EF = AB/DE
21/14 = AB/10
AB = 21/14 * 10 = 15 cm

Viefleur [7K]

Answer:

1. 43/36

2. 1/2

Step-by-step explanation:

1. 7/9 + 5/12

= LCM of 9 and 12 is 36

= 28/36 + 15/12

= (28 + 15) / 36

= 43/36

2. 21/24 - 3/8

= LCM of 24 and 8 is 24

= 21/24 - 9/24

= (21 - 9) / 24

= 12/24

= 1/2

A boat travels 45 miles east then 60 miles north, how far is it from where it started. Draw this. The hypotenuse of the right triangle is the square root (45^2)+(60^2)=square root of 2025=3600=square root of 5625, or 75 miles.
