Here are two different patterns made out of the same five identical isosceles triangles. Without using a protractor, determine the measures of angle x and angle y. Explain or show your reasoning.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

its an acute right triangle
