Answer:
D. Isosceles triangle
Step-by-step explanation: Triangles have 180 degrees. To figure out this question you have to find the measure of the last angle. 70+55=125. 180-125=55. So the angles are 70, 55, 55. In an isosceles triangle two sides are equal. Because we know that two angles in the triangle are equal we then know that two sides of the triangle are also equal. Hope this helped :)
(i) Pairs of <em>neighboring</em> angles are <em>supplementary</em> and <em>opposite</em> angles have the <em>same</em> measure.
(ii) The two angles formed by a line coming out of another line are <em>supplementary</em>.
<h3>
How to analyze pairs of angles</h3>
(i) When two <em>straight</em> lines pass through each other, then <em>two</em> pairs of <em>opposite</em> angles are constructed. A pair with angles of and another pair with angles of , each pair of angles with <em>different </em>measures are <em>supplementary</em>.
(ii) When a <em>straight</em> line comes out of another <em>straight</em> line, from a point distinct to any endpoint of the former, then we construct two <em>supplementary</em> angles. The <em>largest</em> angle has a value of , whereas the <em>smaller</em> one has a value of .

Range is just input the domain
so find f(-2), f(0) and f(2)
f(-2)=-(-2)²+1=-4+1=-3
f(0)=-(0)²+1=0+1=1
f(2)=-(2)²+1=-4+1=-3
range={-3,1}
4+I-15I÷3
4+15÷3
4+5
9
The answer is 9
