What activities are the examples there’s nothing there
1st pic
It's a rhombus
- <span>None of the angles are 90 degrees (can't not be rectangle or square)
- Opposite angles are equal
Top triangle
180 - ( 72 + 72 )
=180 - 144
= 36
same as bottom triangle....
-----------------------------------
2nd pic.
Rhombus...
opposite angles are equal
so m<1 = m<2 = 160
180 - 160 = 20
m< 3 = 20/2 = 10
answer
</span>m<2 = 160
m<3 = 10<span>
-----------------------------
3rd pic.
</span> <span>isosceles trapezoid
</span>
<span>The legs are congruent by definition
</span>
so AB = CD
7y - 4 = 8y - 18
7y - 8y = -18 + 4
- y = -14
y =14
answer y = 14
-----------
pic 4
A(-5, -1), B(-9, 6) C (-1, 5) D(3,-2)
A(-5, -1) and C (-1, 5) ---find slope of 1st pair
slope = (5 + 1)/(-1 + 5) = 6/4 = 3/2
B(-9, 6) D(3,-2)---find slope of 2nd pair
slope = (-2 -6)/(3+9) = -8/12= -2/3
slope of 2nd pair (-2/3) is negative and reciprocal of the 1st pair (3/2)
so it's perpendicular
So first of all you'd want to convert the miles to yards. So 139 miles is 244640 yards. Then you'd have to divide that by 3600, because that's how many seconds are in an hour. This is about 68 yd/s
Answer:
365.76
Step-by-step explanation:
If 2 feet is 60.96, then 1 foot is 30.48.
30.48 times 12 = 365.76
365.76 centimeters is the answer.
Hope this helps!

Answer:
3 2/5 cups remaining
Step-by-step explanation:
To subtract fractions, they need a common denominator. I am using 5.
7 is equal to 35/5. Make 3-3/5 into an improper fraction of 18/5.
Now subtract: 35 - 18 = 17. There is 17/5 remaining.
Make it into a mixed number and you will get 3 2/5 remaining.
