Answer:
x=175
Step-by-step explanation:
The sum of all the degrees in a triangle is 180. First, you have to rind what the third degree of the triangle is. We will call this y.
85+90+y=180
175+y=180
y=5
The floor is flat, so it will be 180 degrees, therefore, x+y=180. We can substitute 5 in for y, so 5+x=180.
So, x would be 175.
It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer. Based on the given scenario above about what Annabelle did, the kind of statistical investigation that she performed was a SURVEY. Hope this helps.
The S in supplementary<span> can be used to form the 8 in 180. The C in </span>complementary <span>can be used to form the 9 in 90. If we know that a set of </span>angles<span> form one of these special relationships, we can determine the measure of the other </span>angle<span>. To determine the supplement, subtract the given </span>angle<span> from 180.</span>
