Really lovely.
Looking at the angles y and (2y-6), they are opposite interior angles of two parallel lines. Their sum is 180.
y + (2y -6) = 180
3y - 6 = 180
3y = 180 + 6
3y = 186 Divide both sides by 3.
y = 186/3 = 62. y = 62.
y + w = 180 sum of angles on a straight line.
62 + w = 180
w = 180 -62 = 128
w = 128.
Looking at the triangle:
w + z + 30 = 180 Sum of angles in a triangle, substituting w.
128 + z + 30 = 180
z + 158 = 180
z = 180 - 158 = 22.
z = 22.
x = z Alternate angles between parallel lines are equal.
but z = 22.
Therefore, x = 22.
Cheers.
Answer:
b = 16.5; 13; 9.5; 6; 2.5
Step-by-step explanation:
Subscribe the given information to get an Answer.
b = 39 / 2 - 3 = 16.5
b = 32 / 2 - 3 = 13
b = 25 / 2 - 3 = 9.5
b = 18 / 2 - 3 = 6
b = 11 / 2 - 3 = 2.5
Answer:
Step-by-step explanation:
R = (5+T)P/3

3R/ (5+T) = P
Answer:
<h2>34 earrings</h2>
Step-by-step explanation:
Step one:
given that the total lenght of the wire is 25 1/2 inches
in decimal, this is 25.5 inches
we are told that each earring requires 3/4 in of wire
in decimal this 0.75 in
Step two:
<em>The number of earrings that can be mad is found by dividing the total length of wire by the length needed to make one earring</em>
The number of earrings that can be made is given as
=25.5/0.75
=34 earrings
Answer:
option a)
y = m(0.5) + 1.8
Step-by-step explanation:
Equation
<h3>
y = mx + c</h3>
represent the equation of straight line
here m = gradient of straight line
c = y-intercept
First find the gradient of the graph
<h3>
m = y2 - y1 / x2 - x1</h3>
= 4 - 3 / 4 - 2
= 1 / 2
Put the values in the equation of straight line
y =mx + c
4 = 1/2(4) + c
c = 2
y = 1/2x + 2
which is approximately equal to y = 0.5x + 1.8
