Since the triangles make up a spinner, the triangles are isosceles.
The base is 2 cm and the perimeter is 10 cm.
The measure of the two legs can be determined from
2 + 2x = 10
Where is the length of the leg
Solving for x
x = 4
The area an isosceles is calculated using
where b is the length of the base
Substitute the values and multiply with the number of triangles in the spinner
Y=21/7
Explanation
7(y/7)=7(3/17)
y=7(3/17)
Multiple
y=21/7
maybe if you divide 3 by 105 and take that answer and subtract from 180 it might give you the answer
We have that
<span>2x + y = 4
to graph this equation </span><span>we will look for the x and y intercepts
step 1
find the x intercepts
y=0
2x+0=4-----> x=4/2-----> x=2
the point is (2,0)
step 2
</span>find the y intercepts
x=0
0+y=4-----> y=4
the point is (0,4)
step 3
with the two points graph the line
see the attached figure

Which TWO expressions are equivalent to<em> </em><em>(x - y) </em>2/3 - 3/4 <em>(y-x)</em>
