Answer:
C. 189
Step-by-step explanation:
Each triangle is 27 which makes it 108, and 108+81=189
Number one: Just plot down on the number like the numbers you have. Just took the test for this.
2. measurements can be any to complementary angles.
for example, 60 & 30
3. the 2 sides are equal. Since it is an isosceles triangle.
4.an equi.triangle can never be right angled. Since, all angles are 60° in an equi.triangle.
5. right triangle can never have an obtuse angle since one angle is already 90°. therefore the other two agles are supposed to be acute angles.[ since sum of all angles in a triangle is 180°]
