The triangle is equilateral (all lengths are the same) therefore the sum of all three angles would equal to 180 degree. Theta 1 would equal to (180/3)=60

In the second part of the problem it's good to assume the shape as a piece if a circle. Which has a radius =1.

The circumference of the circle is 2*22/7*1 = 6.29

Circles have a 360 degree angle and here this circle have a circumference of 6.29. The length of 1 from the circle will be = (360/6.29)*1= 57.3 degree

Thete 2 =57.3

Dear Beruc1,

Thank you. The question it was asking me was to Find θ1,θ2, and θ1 − θ2.

this is the full question. "Two wood sticks and a metal rod, each of length 1, are connected to form a triangle with angle θ1 at the point P, as shown in the first figure below. The rod is then bent to form an arc of a circle with center P, resulting in a smaller angle θ2 at the point P, as shown in the second figure. Find θ1θ2, and θ1 − θ2.

θ1 is one angle of the equilateral triangle so it's 60
Needs to be solved assuming a circle and θ2 will be 57.3 and now you can substract each other
