There are a lot more problems but here are a couple to help you for now.
An=A1+(n-1)d
-20=A1+(15-1)x-7
-20=A1+14 x -7
-20=A1-98
+98 +98

-20+98=78
A1=78
<h2>Area = 80 ft²</h2><h2>------------------------------</h2>
<u>Step-by-step explanation:</u>
diagonal 1 (d1) = 5 + 5
= 10 ft
diagonal 2 (d2) = 8 + 8
= 16 ft
area of rhombus = 1/2 × d1 × d2
= 1/2 × 10 × 16
= 80 ft²

Answer:
x = 54
y = 114
Step-by-step explanation:
y = 114 because of the Corresponding Angles Theorem:
"If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent."
(x + 12) + y = 180
x + 12 + 114 = 180
x + (126 - 126) = (180 - 126)
x = 54
Quick Check:
54 + 12 + 114 = 180 ✔
