its good to know if a number is positive or negative because something as simple as forgetting the signs such as - + could drastically change your answer
Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24
Answer:
it's the last one i mean 4&1/4
Answer: Q = 124 and P = 29
Step-by-step explanation:
Triangles always = 180 degrees so do straight lines.
Answer:
The last one
Step-by-step explanation:
So 2 * -5 = -10
ITS -10 BECAUSE WHEN MULTIPLYING A EGATIVE AND POSITIVE NUMBER THE ANSWER IS ALWAYS A HEGATIVE.
So the last one is the best answer.
