Answer:
x=45 degrees
Step-by-step explanation:
You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.
so 2x+90=180 degrees
so 2x=90 degrees
x=45
Answer:
0.875
Step-by-step explanation:
Answer:
100/150 simplified to lowest terms is 2/3.
Step-by-step explanation:
ln isosceles triangle both sides are equal and the total of all the angles in a triangle is 180 degree so the third angle will be
[180-(79+79)] degrees
=22degrees
