To find angle BCD, find the angle ACB that lies next to it on the straight line first.
Angles in a triangle add up to 180.
To find angle ACB:
180 - 83 - 47 = 50
So angle ACB = 50.
Angles on a straight line add up to 180 as well.
So to find angle BCD:
180 - 50 = 130
So angle BCD = 130, so the answer is D.
Answer:
Step-by-step explanation:
From the above question, we are solving for an Algebraic Equation
2(3x - 4) + 5x = -41 = Given
(6x - 8) + 5x = -41 Distributive Property. 6x + 5x – 8= -41
11x - 8 = -41 Write an equivalent equation
11x = -33 Addition of Property of Equality
x = -3 Division Property of Equality
The reason that is missing from the proof is:
Answer:
v = -2
Step-by-step explanation:
-9v – 9 = -27
add 9 to each side
-9v – 9+9 = -27+9
-9v = -18
divide by -9
-9v/-9 = -18/-9
v = 2
<span>y = 2x + 20. The answer is A. Explanation: Vlad spends a known amount of time on his history homework (20). On top of it, he also spends an unknown amount of time on solving a number of math problems (x). Each problem takes two minutes to solve, so the amount of time that he spends solving math problems is 2*x or 2x. In total (y), Vlad spends 20 + 2x amount of time on his homework. So y = 2x + 20, where y is clearly greater or equal to 20 and x is greater or equal to 0.</span>
