!!I’LL GIVE BRAINLIEST!! What additional information would you need to conclude that DE is the perpendicular bisector of AC?
Answers
Answer:
I believe that the answer is NONE the right angle at B should be enough information to prove that DE is ⊥ to AC
Step-by-step explanation:
By the Side-Angle-Side postulates, the triangles ΔABD and ΔCBD are congruent to each other.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
If two triangles are congruent, then the ratio of the corresponding sides will be ONE.
The line DE is the perpendicular bisector of AC. Then we have
In triangles ΔABD and ΔCBD,
DB = DB (Common side)
∠ABD = ∠CBD = 90°
AB = BC (Bisector length)
By the Side-Angle-Side postulates, the triangles ΔABD and ΔCBD are congruent to each other.

Step-by-step explanation:
The number after the decimal is the tenths place. And the second number after the decimal is in the hundredths place. And so on...
So .98 would be in the hundredths place making it 98/100.

√97 units
Step-by-step explanation:
AB represents the largest side of the triangle so in order to solve for that side, use Pythagorean Theorem.
Pythagorean Theorem: a^2 + b^2 = c^2
where a = height b = base and c = the largest side
Step 1. Find the length of AC (represented as a)
Answer: 9 units
Explanation: either count how many units or use the distance formula
Step 2. Find the length of CB (represented as b)
Answer: 4 units
Explanation: either count how many units or use the distance formula
Step 3. Substitute a for 9 and b for 4 units in Pythagorean Theorem
9^2 + 4^2 = c^2
Step 4. Simplify the exponents
81 + 16 = c^2
Step 5. Solve for c^2
c^2 = 81 + 16
c^2 = 97
Step 6. Square root c^2
c = √97

Answer:
x = 70
Step-by-step explanation:
To find the value of x we need to
we know that the figure is an isosceles triangle so the base angles will be equal
we also know that angle sum of triangle is 180
so
40 + x + x = 180
40 + 2x = 180
2x = 180 - 40
2x = 140
x = 140/2
x = 70

????? what is the value of c?
Answers
Answer:
X=64°
Step-by-step explanation:
Solution,
x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.
x+54°-54°=118°-54°
x=64°
Answer:
64 degrees
The Process:
54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

dy/dx y = 3root(4x+1) -2x
Answers
Answer:
Step-by-step explanation:
y = 3(4x + 1)^1/2 - 2x
dy/dx = 3*1/2(4x + 1)^-1/2 * 4 - 2
= 4 * 1.5 (4x + 1)^-1/2 - 2
= 6(4x + 1)^-1/2 - 2
= [6/√(4x + 1)] - 2
y = 3(4x + 1)^1/2 - 2x
∫3(4x + 1)^1/2 - 2x . dx
= 3 * 1/4 * (4x + 1)^3/2 / 3/2 - x^2 + C

Answer:
pi*z^2*a or "pizza"
Step-by-step explanation:
The dimensions given describe a cylinder, for which the basic volume formula would be base x height.
The base would be a circle, with the radius z as given while the height is a.
The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.
Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a
Side note:
z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".
