Four switches may be modeles as:
_ _ _ _, where you can put one of two marks (off or on) on any _.
So, the number of different ways will be 2 * 2 * 2 * 2 = 16
Answer: 16 possible settings.
Answer:
4.) SAS
Step-by-step explanation:
to sides are congruent and both angles are 90 degrees
Answer:
So, we can say that the square root of 39.24 is 6.264 with an error smaller than 0.001 (in fact the error is 0.0003162785).
M∠BPD = 130° and mBC + mAD = 100°.
An angle formed by two chords has a measure that is 1/2 the sum of the chords.
Here, we know that arc CA = 170° and arc BD = 70°. That means that the sum of CB and DA is 100°. This also tells us that ∠DPA = 1/2(100) = 50°. Therefore m∠BPD = 180-50 = 130°, since it forms a straight angle with ∠DPA.
