Answer:
Yes, it is a right triangle.
Step-by-step explanation:
slope of AB -> (5 - 3) / (0 + 6) = 2/6 -> 1/3
slope of BC -> (-1 - 5) / (2 - 0) = -6/2 -> -3
This already proves that it has a 90 degree angle at angle B because the slopes are inverse and reciprocal. A slope of 1/3 and a slope of -3 (inverse slopes) means that the lines are perpendicular to one another and form a 90 degree angle
Answer:
x = 4, TU = 22
Step-by-step explanation:
Given that TS bisects TU at Q , then
TQ = QU , substitute values
5x - 9 = 15 - x ( add x to both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Thus
TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22

Answer:
RULES:
Half of your diameter is ALWAYS your radius.
15 divided by 2 = 7.5 cm
6.5 divided by 2 = 3.25 in.
3 divided by 2 = 1.5 ft
8 divided by 2 = 4 m
Equation is :
( x + 2 )² + ( y - 1 )² = r²
( - 4 + 2 )² + ( 1 - 1 )² = r²
4 = r², than we will plug in to a formula:
( x + 2 )² + ( y - 1 )² = 4
x² + 4 x + 4 + y² - 2 y +1 = 4
x² + y² + 4 x - 2 y + 1 = 0
