Answer:
7 cm, 4.4 cm
Step-by-step explanation:
The side lengths can be found from the law of cosines. Each triangle has legs 3 cm and 5 cm. The angle between these will be 60° or 120°. Then the two sides of the parallelogram are ...
s = √(a² +b² -2ab·cos(C))
s = √(3² +5² -2·3·5·(±1/2)) = √(34 ±15) = {√49, √19}
The two side lengths are 7 cm and about 4.4 cm.
Answer:
11
Step-by-step explanation:
11 + 8 + 14 + v + 8 + 14
================== = 11 Combine Terms
6
(55 + v) / 6 = 11 Multiply by 6
55 + v = 11 * 6 Combine the right
55 + v = 66 Subtract 55
55-55+v = 66- 55
v = 11
