Answer:
Wha-?
Step-by-step explanation:
The equation of a circle is (x - a)² + (y - b)² = r², where the coordinates of the center(C) are C(a,b) and "r" the radius. Here, C(4,2) and if you need, r=3.
Thanks for your trust!!
Answer: the x axis because its positive 2, -1 the first number is positive
Answer:
The sum of the interior angles of a triangle is 180 degrees.
d. Scalene
e. Isosceles
f. Isosceles
g. Equilateral
h. Scalene
i. Equilateral
j. Right
l. Acute
m. Obtuse - doesn't add to 180 not a triangle
n. Acute - doesn't add to 180 not a triangle
o. Obtuse
Step-by-step explanation:
The interior angles of a triangle add to 180 degrees. There are two ways we classify triangle by side lengths and angle measures.
Side lengths: Compare the side lengths and see if any are equal to determine the type.
- Scalene: 3 different lengths
- Isosceles: 2 equal lengths and 1 different
- Equilateral : 3 equal sides
Angle Measures: Compare the angles measures to 90 degrees.
- Right: If one angle is equal to 90
- Acute: All angles are less than 90 degrees
- Obtuse: One angle is greater than 90 degrees
