2.What is the perimeter of an isosceles triangle that has two sides that are 10 inches long and a base that is 50% as long as either side? (An isosceles triangle is a polygon with 3 sides in which two of the sides are the same length.)

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
