Answer:
Step-by-step explanation:
Sum of all three angle in a triangle=180
Given angles are 35°,45°
Let the remaining angle =x
So 35 +45+X=180
X=180-80
X=100°
Remaining angle =X=100° is the answer
20,000 Hz = 2 × 10^4 Hz
150,000 Hz = 1.5 × 10^5 Hz
Answer: 34 + 2 = 36
Step-by-step explanation:
36 - 2 = 34
Add 2 to this:
36 - 2 + 2 = 34 + 2
36 = 34 + 2
49 = -7 (t + 1)
49 = -7t + 7
-7 -7
42 = -7t
÷ -7 ÷ -7
-6 = t
t = -7
