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.
Answer:
Step-by-step explanation:
42cm=420mm That's times 10
.837kg=837g That's times 1000
89milliliter=.089liters That's divided by 1000
.72meters=.00072 That's divided by 1000
267cm=.0027 kilometers divided by 100,000
Speed = Distance ÷ Time
Time = Distance ÷ Speed
Distance = Speed × Time
Speed = 7/45
Speed = 0.16mph
5/0.16=31.25 more minutes
Answer:
x = -15
Step-by-step explanation:
3x-5=2(2x+5)
Expand by using distributive property
3x - 5 = 4x + 10
Subtract 4x from both sides
3x - 5 - 4x = 4x + 10 - 4x
Simplifying
-x - 5 = 10
Add 5 to both sides
-x - 5 + 5 = 10 + 5
Simplifying
-x = 15
Divide both sides by -1
x = -15
