Answer:
c.
Step-by-step explanation:
To find slope, y2-y1/x2-x1
9-6/-3-(-9)=
3/6= 1/2
Slope = 1/2.
Y=1/2x.
8 x 2 1/4 = 18
the stack is 18 in. thick.
Hope this helps!!

Answer:
Step-by-step explanation:
Area = 1/2(b×h)
b = 18, h = 8
Area = 1/2(18×8)
Area = 18 × 4
Area = 72 square inches
The measure of ∠4, ∠3 and ∠7 are 115°, 65° and 65° respectively.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
∠2 + ∠4 = 180° (sum of angles in a straight line)
∠4 + 65 = 180
∠4 = 115°
b) ∠2 = ∠3 (vertically opposite angles)
∠3 = 65°
c) ∠3 = ∠7 (corresponding angles)
∠7 = 65°
The measure of ∠4, ∠3 and ∠7 are 115°, 65° and 65° respectively.
