The first thing you need to do is add and then subtract
Answer:
41°
Step-by-step explanation:
the sum of the interior angles is 180 degree
so,
38 + x + 101 = 180
139 +x = 180
x = 180 - 139
x= 41°
Answer:
Ratio = 5/3
The ratio (larger to smaller) of the perimeters is 5/3
Step-by-step explanation:
Attached is an image of the two triangles.
Since both triangles are similar, the ratio of their perimeter is equal to the ratio of each similar sides.
Ratio = P1/P2 = S1/S2
Similar side for triangle 1 S1 = 15ft
Similar side for triangle 2 S2 = 9ft
Substituting the values;
Ratio = 15ft/9ft = 5/3
Ratio = 5/3
The ratio (larger to smaller) of the perimeters is 5/3
