The possible values of a, the base of an isosceles triangle, and b, one of the legs of the triangle, are as follows: 26≤a≤28 and 41≤b≤43 (in millimeters). find the possible values of the perimeter of the triangle.

First, you should try to find the sum of the two legs. Because the triangle is isosceles so the legs (b) are equal, than the sum of the two legs:

41*2 ≤ 2b ≤ 43*2 simplified is: 82 ≤ 2b ≤ 86

But we aren't done, for the perimeter also includes the base of the triangle, which is a. Since we already know the sum of the legs, we simply have to add the base (a) to the legs.

Sum of Legs:         82 ≤ 2b ≤ 86

Base:                      26 ≤ a ≤ 28

Perimeter (a+2b):   82+26 ≤ P ≤ 86+28     Which simplified:   108 ≤ P ≤ 114

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
