The answer would be - B. All real numbers
Answer:
Step-by-step explanation:
a² + b² = c²
3.6² + b² = 7.4²
b² = 7.4² - 3.6² = 41.8
b = √41.8
Since a triangles angles add up to 180 you would add the other sides and then
180-161=19
So angle 1 is 19 degrees
Answer:
x = -7/4
Step-by-step explanation:
"Eight times a number equals 4 times that number less 7."
Subtracting 4x from both sides of this equation, we get:
4x = -7
Dividing both sides of this result by 4 yields
x = -7/4
