In the diagram below of triangle ABC, medians AD, BE and CF intersect at point G
If the length of AD is 48 cm, how many centimeters long would DG be?
Answer:
DG = 16 cm
Step-by-step explanation:
DG is one- third of AD , then
DG = [tex]\frac{1}{3}[/tex] × 48 = 16
The length of the segment DG will be equal to 16 cm.
What is geometry?Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial qualities such as figure distance, shape, size, and relative position. A geometer is a mathematician who works in the field of geometry.
Given In the diagram below of triangle ABC, medians AD, BE and CF intersect at point G and the length of AD is 48 cm.
The length of the segment DG will be calculated as,
DG is one-third of AD, then
DG = ( 1 / 3 ) × 48
DG = 16
Therefore, the length of the segment DG will be equal to 16 cm.

One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60
Answer:
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
From the above question, one of the angles = 60°
The value for the two other interior angles = 180° - 60° = 120°
Hence, the following options could be the values of x and y is given as x + y = 120
Therefore,
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60

Triangle BCD is isosceles and BC ≅ BD. Circle A is shown. Isosceles triangle C B D has points on the circle. The lengths of C B and B C are congruent. The measure of arc C D is 100 degrees. What is the measure of Arc B C? 100° 120° 130° 160°
Answer:
130
Step-by-step explanation:
since bc and bd equal the same thing, plug in every answer option until you get to 360.
(130 x 2) = 260
plus cd = 100.
260 + 100 = 360.
The arc length is twice the inscribed angle.
The sum of the three angles must be 180.
The measure of the arc length BC is 130°
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle BCD is isosceles and BC ≅ BD.
Isosceles triangle C B D has points on the circle.
The measure of arc CD is 100 degrees.
This means,
We know that the arc length is twice the inscribed angle.
2 x Angle B = CD
2 x Angle B = 100
Angle B = 100/2
Angle B = 50
Now,
In an isosceles triangle, the angle opposite to the equal sides must be equal.
The sum of the three angles must be 180.
x + x + 50 = 180
2x = 180 - 150
2x = 130
x = 65
Now,
We know that the arc length is twice the inscribed angle.
So,
The measure of the arc length BC.
= 2 x 65
= 130°
Thus,
The measure of the arc length BC is 130°

⦁ Convert the vertex form of the equation you wrote above to standard form.
the vertex was ax+b(?)
Answer:
ax^2 + bx + c
Step-by-step explanation:
im pretty sure this answers your question
The standard form of the vertex form equation is y = 2x² - 12x + 17
How to convert the equation?The vertex form of a quadratic equation is represented as:
y = a(x - h)² + k
Using the above form, the quadratic equation can be represented as:
y = 2(x - 3)² + 1
Expand
y = 2(x² - 6x + 9) - 1
Further expand
y = 2x² - 12x + 18 - 1
Evaluate the like terms
y = 2x² - 12x + 17
Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

Which of the following is a solution to the equation y=-1/4x +8 O (10,8) 0 (48) O (49) O (-8.-10)
Answer:
Step-by-step explanation:
The last one -- D -- is the closest correct answer. None of them, however, is right.
y = -1/4 x + 8 Let x = - 8
y = -1/4 * - 8 + 8 The standard rule is starting from the left, do the multiplication first then do the addition
- 1/4 * - 8 will first of all give you a positive result. When 2 minuses are multiplied they give a positive answer.
-1/4 * - 8 = 1/4 * 8
1/4 * 8 = 2
y = 2 + 8
y = 10
So the ordered pair (-8 , 10) is the answer.
