LenKa [72]4 years ago
7 0

Answer:

33.3333% decrease

Step-by-step explanation:

Percent change formula: \frac{(x-y)}{|y|} *100, where x is the new value and y is the starting value.

Plug in values and solve:

\frac{20-30}{30} *100\\\frac{-10}{30} *100\\-0.3333*100\\

-33.3333% change, or a 33.3333% decrease.

We have an inscribed angle here. Angle YXZ is an inscribed angle.

Angle YXZ can also be expressed as simply angle x but I will use angle YXZ.

Angle YXZ = (1/2)(arc YZ)

Angle YXZ = (1/2)(144°)

Angle YXZ = 72°

Done!

uysha [10]

Answer:

All four options are correct.

Step-by-step explanation:

Option 1

m∠DPQ = m∠FQB = 90° [Corresponding angles theorem]

By the converse property of corresponding angles theorem,

CD║EF

Since, angle between AB and CD is 90°,

AB⊥CD

True

Option 2

Since, angles between AB and EF is 90°, both will be perpendicular.

AB ⊥ EF

AB ⊥ CD

True

Option 3

CD║EF and AB ⊥ EF

True

Option 4

CD║EF, AB ⊥ CD and AB ⊥ EF

True

Therefore, all options are correct.
