A triangle with an acute angle measuring 7 cm and the length of the triangle is 13 cm what is the length of the missing side?

In an acute triangle, if the largest angle measures 89.99 degrees, and two of the sides are 7 and 13 centimetres, then the remaining side will be 10.96 centimetres.

Other lengths are possible, but without knowing the magnitude of at least one of the angles, it is impossible to list them all here. the answer is 218 cm. you have to take 7 times 7 =49,then you take 13 times 13 =169,then you add the two figures together to get the answer 218 cm
