One geometry question
Please help me with this

∠ XAZ = 50°

Step-by-step explanation:

The measure of the circle = 360°

Given arc XYZ = 230°, then

arc XZ = 360° - 230° = 130°

The tangent- tangent angle XAZ is one half the difference of the intercepted arcs, that is

∠ XAZ = (230 - 130)° = 0.5 × 100° = 50°

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

i think this could be a possible answer (1 / 84) -1

good luck! : d
