A circle is described by the equation x2−10x+y2+8y=6

Mathematics
1 answer:
Rina8888 [55]3 years ago
3 0

x² - 10x + y² + 8y = 6

x² + y² - 10x + 8y - 6 = 0

Center = (-(1/2)A, -(1/2)B)

= (-(1/2)(-10), -(1/2)(8))

= (5, -4)

Radius = √((1/4)A² + (1/4)B² - C)

= √((1/4)(-10)² + (1/4)8² - (-6))

= √((1/4)(100) + (1/4)(64) + 6)

= √(25 + 16 + 6)

= √47

In paragraph for m, explain how one may determine when two triangles are congruent.give a diagram with labels and details to sup
Anon25 [30]
A pair of congruent triangles will have the same three side lengths and the same the angles. The equal sides and angles may not be in the same position due to turning or flipping, but they are always there. You can draw a phone with congruent lines on each triangle.

Find the ratio of two complement angle is 2:3. Find the angles.​
Aliun [14]

Answer:

The angles are 2x= 2x18°   =36° and  3x=3×18   =54°  

Step-by-step explanation:

It is given that two complementary angles are in the ratio 2:3.

Consider 2x and 3x as the angles.

We know that, if two angles are complementary, then their sum is 90°    .

Then, 2x+3x=90°  

 ⟹ 5x=90°  

⟹ x=  90/5

​  x=18°  

Here, the angles will be 2x=2×18   °=36°  

 and 3x=3×18°   =54  °

Hope this helps.
