X and y are opposite angles therefore x=y.
The sum of the measures of the interior angles of a triangle is 180 degrees:
y+55+30=180
y=180-55-30
y=95 degrees
so:
x=y=95 degrees
The answer is nine: 17 minus 8 is 9
The probability of drawing a black marble is 7/31 or .226 or 22.581%. To find the probability of these type of questions, add all together to get 31, then since there are 7 black marbles the probability would be 7/31.
Answer:
A (0, - 2 ) or A (0, 6 )
Step-by-step explanation:
Using the distance formula
d =
with (x₁, y₁ ) = B(3, 2) and (x₂, y₂ ) = A(0, y )
AB =
=
=
Given AB = 5 then equating gives
= 5 ( square both sides )
9 + (y - 2)² = 25 ( subtract 9 from both sides )
(y - 2)² = 16 ( take square root of both sides )
y - 2 = ± = ± 4 ( add 2 to both sides )
y = 2 ± 4
Then y = 2 - 4 = - 2 or y = 2 + 4 = 6
Possible coordinates of point A are
A (0, - 2 ) or A (0, 6 )
Answer:
Step-by-step explanation:
The perimeter of a rhomboid: The perimeter of a rhomboid is the sum of all sides of the figure i.e. P= (a +b + a +b) = 2(a + b).
B is the base of the rhomboid and a is the length of the side of the rhomboid.
