Answer:
Step-by-step explanation:
In a triangle the sum of all angle measures is always 180 degrees
degrees
By splitting the isosceles triangle down the middle we can calculate the base
So ∠H = 23°, ∠K = 90°, ∠J = 67°, HJ = 19
With this we can solve for half of the base. the trig function will need to use is sin, since the side opposite of ∠H will be part of the base.
now we need to rearrange the formula for what we have.
This value is only half of the base, so we need to double it
