when you have 2 negative numbers you actually add the 2nd number to the first one
example:
-4 - -2 = becomes -4 + 2 = -2
Answer:
the answer would be A because the x's are 1's
Answer:
6sqrt(5)
Step-by-step explanation:
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.
