In circle O, what is m∠MAJ? °
mr_godi [17]

See the attached figure.

m ∠KAJ = 170° &  m ∠LAM = 80°

We should know that :

m ∠KAJ + m ∠LAM + m ∠KAL + m ∠MAJ = 360°

∴ m ∠KAL + m ∠MAJ = 360° - (m ∠KAJ + m ∠LAM)

∴ m ∠KAL + m ∠MAJ = 360° - (170°+80°) = 360° - 250° = 110°

But : m ∠KAL = m ∠MAJ ⇒⇒⇒ <u>Opposite angles.</u>

∴ m ∠MAJ + m ∠MAJ = 110°

∴ 2 * m ∠MAJ = 110°

∴ m ∠MAJ = 110° ÷ 2 = 55°


<u>So, the answer is :  m ∠MAJ = 55°</u>

What is the answer please please help me
zmey [24]
Part A: the answer is C. They only converted milligrams to grams instead of going to kilograms. There are 6 steps between milligrams and kilograms, so 25,000 should've been divided by 1,000,000.
Part B
9.58 kg+1.25 kg+0.025 kg = 10.855 kg
So the bag, water bottle, and sleeping bag weigh 0.145 kg less than 11 kg
