X = 90 degreees, so you take 47 and 90 add them together and you get 137 degrees. you need 180 to make a triangle, so you subtract 137 from 180. the answer for y is 43 degrees. hope that helps
So add
1/5+3/8
convert bottom number to same number
5 times 8=40
bottom mub be 40
1/5 times 8/8=8/40
3/8 times 5/5=15/40
add
1/5+3/8=8/40+15/40=(8+15)/40=23/40
so completed 23/40 total
Answer:
z=7
Step-by-step explanation:
area = ½ × (a + b) × h.
260 = 37 + 4z × 8 ×0.5
260/0.5 = 520
520/8=65
37 + 4z = 65
65-37 = 28
28/4=7
z=7
The equation for the sum of interior angles is :
Sum = (n-2) x 180, where n is the number of sides.
Replace sum with the given sum:
3960 = (n-2) x 180
Divide both sides by 180:
22 = n-2
Add 2 to each side:
24 = n
It has 24 sides.
For Each interior angle, divide the total sum by the number of sides:
3960 / 24 = 165 degrees
The interior and exterior angle needs to equal 180 degrees. To find the exterior angle, subtract the interior angle from 180:
180 - 165 = 15 degrees.
