Answer:
90
Step-by-step explanation:
all triangle have an interior angle sum of 180 degree
iscocolese triangles have two equal sides meaning 2x=y=180
the base angles represent x and y is the vertex angle plug in your values and you get the equation 2(45)+y=180
simplify:90+y=180
subtract from both sides to get x by itself: y=90
The measure of the other two angles are 45° and 90°.
A triangle is a three-sided polygon with three edges and three vertices. The sum of angles in a triangle is 180 degrees. An isosceles triangle has two opposite sides. If the two angles are equal.
If one of the base angles of the isosceles triangle measures 45 degrees, the other base angle would measure 45 degrees.
The third angle would measure : 180 - (45 + 45)
180 - 90 = 90 degrees.
