Answer:
a) x = 60. b) b = 110. c) x = 20. d) x = 30.
Explanation:
For question a, 2x and 120° are opposite (vertical) angles so they must be the same measure according to the vertical angle theorem by definition, given they are angles formed by the transversal cutting two parallel lines. 2x = 120, so x = 60.
For question b, 130° and b + 20 are corresponding angles of the transversal cutting parallel lines, so they must be the same measure according to corresponding angle theorem(same side, one angle inner, and the other exterior of that) by definition. Given that they are both pairs of the same angle, they must be corresponding angles. 130° = b + 20, b = 110.
For question c, 120° and 2x + 20 are same side interior angles so they must be supplementary(add up to 180°) by definition. This is on the *same side* of the transversal inside the two parallel lines cut by it. 120° + 2x + 20° = 180°, x = 20°.
For question d, They are also on the same side but on the left so the same property of corresponding angles applies, so 3x + 10, and 100° must be the same measure. Therefore 3x + 10 = 100°, and x = 30.
Answer:
A) The side is 14 cm
B) The total distance around the whoole board is 56 cm
Step-by-step explanation:
So we know its a square.
A square is all equal sides
We got the area which is 196
So we know area of a square is L*W or S^2
And since all sides are equal we can square root 196
That would give you 14
So we know each side is 14
Part B is just perimeter, there are 4 equal sides so we can just multiply 14*4 which is 56.
CHECK:
So we want to check the sides are equal
Each side is 14
and area is 196
14*14=196
So its true
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
