Answer:
Angle B=92
Arc DCB=228
Step-by-step explanation:
Arc DCB intercepts Angle A.
Arc DCB is twice of Angle A so that means Arc dCB=228
Angle C is supplementary so Angle B equal 92.
The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft
<h3 />
<h3>Area of a rectangle:</h3>
where
l = length
w = width
She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,
lw = 1600
Therefore,
perimeter = 160 ft
Then,
perimeter of rectangle = 2(l + w)
160 = 2(l + w)
l + w = 80
Let's combine the equations
lw = 1600
l + w = 80
l = 80 - w
Therefore,
w(80 - w) = 1600
80w - w² = 1600
Therefore,
w² - 80w + 1600 = 0
w² - 40w - 40w + 1600 = 0
w(w - 40) - 40(w - 40) = 0
(w - 40)(w - 40) = 0
w = 40 or 40
Therefore, the dimensions can be calculated as follows:
lw = 1600
40l = 1600
l = 1600 / 40
l = 40 ft
Therefore, the dimensions are 40ft by 40 ft

Is it a written response or a multiple chose question?
Answer:
Triangle 1's answers:
9² + 12² = <u>15²</u>
15² = <u>225</u>
Right Triangle
Trangle 2's answers:
6² + 15² = 
18² = <u>324</u>
Obtuse Triangle
Step-by-step explanation:
The answers to number 1 for each triangle are solved exactly how they are written :).
The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.
Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.
Triangle 2 is an Obtuse Triangle because one side has a way larger angle than the other two angles.
Hope it helps!
