Part B
Using squares 1, 2, and 3, and elght copies of the original triangle, you can create squares 4 and 5 C. Keep the square 4 and
square 5 window open. You will need them to complete the rest of the tasks in this section.
What are the side lengths of square 4 and square 5 in terms of a and b? Do the two squares have the same area?

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
