Solve for a. 7a - 2b = 5a + b a = 2b a = 3b a = a equals startfraction 3 over 2 endfraction b. b a = a equals startfraction 2 over 3 endfraction b. b

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

other answer is correct. i had used the radius of the radius somehow. a website:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
