Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.
The method of successive differences uses subtraction to the one number to the next and the process goes on until the difference settles constant which is not equal to zero. In this case, the constant difference reaches 25. Reversing the process to get the next term, the answer is 2509.
It would be 76% because if you were to put the shaded box in the bottom corner there would be way more than 50% not covered hope this helped
