Answer:
x=90
y=67
Step-by-step explanation:
as the line that bisects the vertical angle of isosceles triangle perpendicularly bisects the base
so x=90
and sum of all sides of triangle is 180 so
90+23+y=180
therefore,y=67

Answer:
Step-by-step explanation:
The two dots on the bottom of this figure define the base of a triangle. If we now use a compass to draw the blue arcs on either side, as shown, the arcs will intersect at two points. A straight line drawn through these two points will be perpendicular to the base. The triangle will be isosceles and could be (but doesn't have to be) equilateral.
Answer:
an = 2/5 * (5) ^ (n-1)
Step-by-step explanation:
The common ratio is 5
(That is the number we multiply by)
The formula is
an = a1 (r) ^ (n-1)
an = 2/5 * (5) ^ (n-1)
