Answer:
m∠4 = 55°
Step-by-step explanation:
From the figure attached,
m∠DBC = m∠BCA + m∠BAC [Exterior angle of a triangle equals the sum of the remote interior angles]
m∠4 = 30° + 25° = 55°
Therefore, m∠4 = 55° will be the answer.
Answer: 1/9 because 1/9 is equivalent to .1 repeating, and since it repeats, it would continue with the 1 for infinite decimal places, thus making 11.11111% because you move the decimal over 2 places to make the fraction turn into a decimal.
x + y = 4(1 + y) + y = 4 1 + 2y = 4 1 - 1 + 2y = 4 2y = 4 y = 2
-x = -1 + y-x = -1 +2
-x = 1
.... that's as far I can go... sorry
D. 36 - just do the reverse of the question, (-12 * 3 = ...)
