Answer:
y = 90°
Step-by-step explanation:
The left side base angle of the triangle and the angle of 110° form a straight angle and are supplementary, thus
base angle = 180° - 110° = 70°
The right base angle is also 70° , thus the triangle is isosceles
The line segment from the vertex is a perpendicular bisector, hence
y = 90°

Answer:
SAS
Step-by-step explanation:
<u>Side</u>
- Two congruent legs on each triangle
<u>Angle</u>
The vertical angle in between makes both of the angles congruent.
Well, equation of circle is (X-X1)^2 + (Y-Y1)^2 = R^2
so, (X-4)^2 + (Y-3)^2 = 25
X^2 + 16 -8X + Y^2 + 9 - 6Y = 25
X^2 + Y^2 - 8X - 6Y = 0
this is the correct answer hope it helped :)

Answer:
There are 180 marbles in the jar
Step-by-step explanation:
Let x = number of marbles in the jar
x * 25% = number of red marbles
x * .25 = 45
Divide each side by .25
x *.25/.25 = 45/.25
x =180
There are 180 marbles in the jar
