Determine whether a triangle can be formed with the given side lengths. if so, use heron's formula to find the area of the triangle. a = 240 b = 121 c = 302

The area of triangle formed by given side lengths is 13724.27.

Step-by-step explanation:

A triangle can be formed If the sum of the other two sides (except largest side) is greater than the largest side that is a+b>c.

Here, given side lengths:

a = 240 

b = 121

c = 302

Here, largest side is c = 302

so taking sum of other two sides,

a+b = 240+121 = 361> 302

Hence, triangle can be formed with a, b and c as given lengths.

Calculating area using Heron's formula,

where s is the semi perimeter

Formula to find semi perimeter is

So, first we find the semi perimeter by using given sides,

Now put the value of s,a,b and c in the Heron's formula,

Therefore, the area of triangle is approx. 13724.27.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
