Answer:
26°
Step-by-step explanation:
90°+64°+x°=180° (Sum of all the angles in a right angled triangle=180°)
154°+x°=180°
x°=180-154°
x°=26°
Answer:
n = -36
Step-by-step explanation:
The answer is -36 because:
1) We first have to subtract -24 and 12 to find n
-24 - 12 = -36
This is because whenever there are two negative signs, multiply it.
Negative x Negative = Positive
We have to do, 24 + 12 which is 36. Finally, we just put the greater number's sign to the answer. 24 is greater than 12, therefore, we put a negative sign before 36.
Hope this helps!
