Answer:
not a right triangle
Step-by-step explanation:
We can use the Pythagorean theorem to see if it is a right triangle
a^2 + b^2 = c^2
15^2 + 12^2 = 21^2
225 + 144 = 441
369 = 441
This is not true so it is not a right triangle
Answer:
Point slope formula: (y + 4) = 2(x - 5)
Slope intercept formula: y = 2x - 14
Step-by-step explanation:
Point slope formula: (y + 4) = 2(x - 5)
Slope intercept formula: y = 2x + b, -4 = 10 + b, b = -14
y = 2x - 14
Answer:
He worked for 3.25 hours
Step-by-step explanation:
29.25 / 9 = 3.25
:D
Answer:
D
Step-by-step explanation:
The inscribed angle x whose vertex lies on the circle and whose sides are chords of the circle is one half the measure of the intercepted arc, thus
x = 0.5 × 102° = 51° → D
