Answer:
y=33 degree
Step-by-step explanation:
y = 33 degree (the relation between y and 33 is they are vertically opposite angles anf verticelly opposite angles are always equal)
Answer:
You simply end up dividing. 48/3 is equal to 16/1 and 56/8 is equal to 7/1
Step-by-step explanation:
48/3, you simply divide, and you end up with 16, therefore, you would place it over the 1
56/8 you would do the same action. Knowing multiplication may help as well.
7*8 is equal to 56
16*3 is equal to 48
hope this helps:)
Answer:
∠ 1 = 65°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
5x - 10 is an exterior angle of the triangle, then
5x - 10 = 3x + 40 ( subtract 3x from both sides )
2x - 10 = 40 ( add 10 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
The sum of the 3 angles in a triangle = 180° , so
∠ 1 + 40 + 3x = 180°
∠ 1 + 40° + 3(25) = 180°
∠ 1 + 40° + 75° = 180°
∠ 1 + 115° = 180° ( subtract 115° from both sides )
∠ 1 = 65°
Y=-1/4x
you can tell because the line is going down if you read it from left to right, so it is a negative slope, and if you looks at 2 points where the line crosses, it goes down one, and to the right four
