What is the measure of each base angle of an isosceles triangle if its vertex angle measures 40° and its 2 congruent sides measure  25 units

70 degrees

Step-by-step explanation:

since an isosceles triangle is symmetrical, i cut the triangle in half (vertically) so that it became a right triangle. so the angle sides are now 20 degrees at the top, 90 degrees (right angle, where it was cut), and x degrees. 20 + 90 + x = 180 degrees (total amount of degrees in a right triangle) x = 70 degrees.

hope this helps!

idk

step-by-step explanation:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
