Answer:
Positive
Step-by-step explanation:
Answer: h = 113°
Step-by-step explanation:
First, we will find the third angle of the top triangle
Which we can call x
43° + 24° + x = 180°
67° + x = 180°
x = 180° - 67°
x = 113°
Now, we can see that x and h are opposite angles
Which means x = h
113° = h
Answer:
13+2h
Step-by-step explanation:
The word "sum" can be related to "addition" and "13 and a number" is just "13" and an exponent.
