Answer:
m∠A + m∠B = 155
Step-by-step explanation:
ABC is an isosceles triangle that has a 130° angle at vertex B
then
m∠A = (180 - 130)/2 = 50/2 = 25 = m∠C
then
m∠A = m∠C = 25°
Answer:
A
Step-by-step explanation:
Got it right on the quiz.
The letter C stands for the Circumference of the circle
X1, y1 = (-5,-3)
x2, y2 = (-5, -6)
distance =√[(x2-x1)^2 + (y2-y1)^2]
=√[(-5 + (-5))^2 + (-6+(-3))^2]
= √(100+81)
=
Answer:
See below.
Step-by-step explanation:
40 + 15x = 30 + 19x
15x - 19x = 30 - 40
-4x = -10
x = 2.5
