Answer:
x=8
Step-by-step explanation:
first you need to find the unknown corner so you do 180-71= 109
then find the interior angle degree (n-2)*180 (n=number of sides) so (4-2)*180=2(180)=360
then set everything equal to 360:
10x+6+13x-2+8x-1+109=360
(combine like terms)
31x+112=360
(subtract 112 form both sides)
31x=248
(divide both sides by 31)
x=8
Area of a triangle can be calculated as:
Area = 0.5 x Base x Height
Area is given to be 52 in²
Height is 13 inches.
We are to find the base b of the triangular shaped guitar.
Using the values in above formula, we get:
Thus the base of triangular shaped guitar will be 8 inches.
