Answer:
Step-by-step explanation:
The first 2 do sum up to 180 degrees, so the first 2 ARE triangles, but i cant see the full question of the 3rd and 4th one.
Answer:
The answer is : 20+5-39= <u><em>-14</em></u> and 5+24-2= <u><em>27</em></u>
Hope this helps!!!!
Step-by-step explanation:
The equation we can use to find the value of x in the diagram given is: B. (5x + 30) + 5x = 90.
<h3>What are Complementary Angles?</h3>
Angles that give a sum of 90 degrees when added are referred to as complementary angles.
The angles, (5x + 30) and 5x are complementary angles, since the sum of both gives a right angle (90 degrees).
Therefore, the equation that we can use to find x in the diagram is: B. (5x + 30) + 5x = 90.

Answer:
4) in question it should be triangleMNP and NOP
reason by SSS axiom
5) reason is as the angles of congurent triangles are equal)
If 1990 is x = 0, then 1997 is x = 7.
Use x = 7 in the equation for the number of taxi accidents.
