Answer: C. 53º, 55º
Step-by-step explanation:
1. By definition, the sum of the interior angles of a triangle is 180 degrees.
2. Keeping this on mind, you have:
As you can see, the sum of the other two angles must be 108 degrees, then, let's add the angles given in each option:
A. 9°+9°=18
B. 26°+46°=72°
C. 53°+55°=108°
D. 72°+108°=180°
3. Therefore, the answer is the option C.
<span>7y - 8 + 6y - 3
= 13y - 11
-----------------
7y + 6y = 13y
(-8) + (-3) = -11</span>
Answer:
8
Step-by-step explanation:
Direct variation should be called linear variation.
In this case, the answer is B.
A has the quadratic variation, C has the inverse variation, D has the cubic variation
Answer: 9-3x
Step-by-step explanation:
You add like terms
don't look at the 3x for now
positive 7 + positive 2 = 9
there is a negative sign next to 3x
9 goes first so
9 - 3x
