Answer:
The base angles are 36° each
Step-by-step explanation:
An isosceles triangle is a triangle that has two of its sides and base angles to be equal.
If an isosceles triangle has a vertical angle of 108°, then the base angles will share the remaining angle in the triangle equally.
Since the sum of angles in a triangle is 180°
The remaining angle in the triangle = 180°-108°
= 72°
Since the base angles are equal, this remaining two angles will share angle 72° equally.
The base angles = 72°/2
The base angles = 36°
This shows that the base angles are 36° each.

Answer:
easy:
6*10 / 2 = 30
6*10 would be a rectangle. a right triangle is just half the area
Good evening ,
Answer:
<h2>(3,15)</h2>
Step-by-step explanation:
y=5x then
4x-y= -3 ⇌ 4x-5x= -3 ⇌ -x= -3 ⇌ x=3
and since y=5x then y=5×3=15.
