There are 180 degrees in a triangle so 180-36 which is 144 and since you’re looking for two angles, you divide 144 by 2 and you get those two angles.
So x=72

Alexeev081 [22]

Answer: \frac{8}{15}

Step-by-step explanation:

Let's re-write 3 as a fraction: \frac{1}{3}

Now all we have to do is multiply the numerator by the reciprocal of the denominator.

\frac{8}{5} * \frac{1}{3}

\frac{8}{5 *3}

\frac{8}{15}

Your answer is: \frac{8}{15}

I hope this helps!

If rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated, how many hours must have passed if there are
zavuch27 [327]

Given :

Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.

To Find :

How many hours must have passed if there are 5 inches of rain .

Solution :

Let , after x hours rain accumulated is 5 inches .

We know , general equation of line :

y = mx +c

Here , m = 0.5 and c = 1 .

So , equation of rain accumulated is :

y=0.5x+1

Now , putting value of x = 5 hours .

We get :

y=0.5\times 5+1\\\\y=2.5+1=3.5\ inches

Hence , this is the required solution .

When 36 is subtracted from the square of a number, the result is 5 times the number. Find the negative solution.
Sloan [31]

Answer:

n = -4

Step-by-step explanation:

If we subtract 36 from the square of that number, X^2 - 36 ...

The result is equal to 5 times the number, 5X

Therefore,

X^2 - 36 = 5X

You've probably seen this solved by putting the equation in the form:

aX^2 - bX - c = 0

Doing that here, we subtract 5X from both sides to make the right side of the equation equal to zero.

X^2 - 5X - 36 = 0

Now we need to factor this.

(X _ _ )(X _ _ ) = 0 (where _ denotes an operator or term that we need.)

Looking at the operators, we see that the operands are different, so

(X - _ )(X + _ ) = 0 (we have operator, need term.)

Now we need to find two factors of 36 whose difference is 5. So let's try a few:

36 = 6 X 6 Nope

36 = 12 X 3 Nope

36 = 9 X 4 Yup!

Since the middle term is negative, we know the placement of the 9 and 4.

(X-9)(X+4)= 0

Therefore, X-9=0 or X+4=0

X-9=0 => X=9

X+4=0 => X=-4

Going back to the original problem, it says "Find the negative solution."

Therefore, X=-4.

Let's check:

(-4)^2-36 = 5*(-4)

16-36 = -20

-20=-20 Check!

60in=60in × (1ft/12in) = 5ft
30in= 30in × (1ft/12in) = 2.5ft
12in = 12in × (1ft/12in) = 1ft
answer is = 5ft × 2.5ft× 1ft =12.5 ft^3 = a

11)
dozen = 12 hammers
12 hammers = 20 pounds
therefore 1 hammer= 20/12 = 1.6666 lb

21 hammers ×1.666 = 35 = c

Carla is 12
rob is 12+5= 17
cousin is 12-7 = 5
