Answer:

D. \triangle BGC is right angle because $\overleftrightarrow{EG}$⊥ $\overline{CC'}$CC'.

Step-by-step explanation:

Given A figure  in which line EG is perpendicular to Segment CC'

Therfore ,\triangle BGC is a right angled triangle because in which \angle BGC=90^{\circ}

A right angled triangle is that type of triangle in which one angle is of 90 degree .Then ,we say the the triangle is a right angled triangle.

Now , we can see from the given figure  in \triangle BGC line EG is perpendicular is given . Hence, we are given

$\overleftrightarrow{EG}$\perp$\overline {CC}'$

\therefore , \angle BGC=90^{\circ}

Hence, we can say the triangle BGC is a right triangle.

Now, we check given option

A. It is false. Because no information about the triangle A'B'C' .In given statement the triangle A'B'C' is the reflect image of the triangle ABC .So we can not say \triangle A'B'C' is a right angle .

B. ADC is a right triangle because $\overline{AA'}  intersect AC at C.

It is false.Because  we can see from given the figure AC not meet in given figure.

C. \triangle BCC' is a right triangel  because B lies of the reflection .It is false.Because we can't say that BCC' is a right angle if B lies of the reflection.

D. \triangle BGC is a right triangle  because $\overleftrightarrow{EG}\perp$\overline{CC'}

It is true.  Because EG is perpendicular it means \angle BGC=90^{\circ}. Hence, we can say triangle BGC is right triangle.

Find the domain and range of the relation: {(–20, 11), (6, –8), (1, –20), (–13, 13)}
user100 [1]

Answer:

D: {-20, -13, 1, 6}

R: {-20, -8, 11, 13}

Step-by-step explanation:

Given the relation, {(–20, 11), (6, –8), (1, –20), (–13, 13)}, all x-values (inputs) make up the domain of the relation while all y-values make up the range of the relation.

Therefore:

Domain: {-20, -13, 1, 6}

Range: {-20, -8, 11, 13}

2.5 cups is half of 5
2 is half of 4

you increased the recipe by 1/2

so for 6 teaspoons you will need 7.5 or 7 1/2 cups of flour b/c 5 + 2.5 = 7.5

Please help it's about Phythagorean Theorem! <br> I attached the image
storchak [24]
Pythagorean Theorem is:

c² = a² + b²

Let’s find the values of a and b.

Looking at the image provided in the question we have 2 number already, 70 and 120.

Let’s name the side with length 120 as a, and the side with length 70 as b.

Then we should substitute these values into the Pythagorean Theorem:


c² = 120² + 70²

c² = 14400 + 4900

c² = 19300

Then we should work out the value of c by square rooting both sides:

√c = √19300

c = 138.92444

Therefore the ball would have to be hit a total of 138.92444 units.

If you have to round, that would be 139 units.
