One of the base angles of an isosceles triangle measures 68º. The base of the triangle measures 13 centimeters. What is the perimeter of the triangle? Round intermediate results to 3 decimal places and
the final answer to 1 decimal place

Step-by-step explanation:

x = 6.5/cos(68°) = 17.352

Perimeter = 2x + 13 = 47.7 cm

21/58.

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
