The perimeter of triangle STU is 28.8 centimeters. Which is the perimeter of triangle JKL?

Find the scale of JKL by using the hypotenuse of both:

St = 12, JL = 4

JKL is 1/3 the size ( 4/12 = 1/3)

Multiply the perimeter of Stu by 1/3

JKL = 28.8 x 1/3 = 9.6 centimeters.

9.6 cm

Step-by-step explanation:

Δ STU and Δ LJK are similar , thus the ratio of corresponding sides are equal, that is

= =

The sides of Δ LJK are the sides of Δ STU, then the ratio of the perimeters is the same.

perimeter of Δ JKL = × 28.8 cm = 9.6 cm

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
