Short answer: x = 40
Remark
All you are concerned about is the bottom triangle. It is isosceles, so the two base angles are equal. You are 1 step away from finding x.

Step one
Find he vertex angle (the top angle) of the triangle
Let the vertex angle = V
V + 70 + 70 = 180 Add the two 70s together.
V + 140 = 180 Subtract 140 from both sides.
V = 180 - 140
V = 40

Step Two
Find x
Since V and x are vertically opposite (you have to assume that or this question is unsolvable) then V = x
x = 40 degrees

Answer
x = 40 degrees

What's the answer to 7x-x

IgorLugansk [536]

Answer:

Step-by-step explanation:

7x - x

X by itself is the same thing as 1x.

So, if we rewrite the equation using 1x instead of just x:

7x - 1x

Now, we can subtract like we normally would.

7x - 1x = 6x

Kallie's mom takes her out for lunch. The bill comes to $18.75. Her mom comments that the waiter did a good job and deserves a 1

slava [35]

Answer:

The tip was actually a little over 15% so we could surely say it is pretty sound and reasonable.

Step-by-step explanation:

To Determine:

Explain how Kallie can mentally estimate whether her mom's tip is reasonable for a 15% tip?

<em>Information Fetching and Solution Steps:</em>

Kallie's mom takes her out for lunch
The bill comes to $18.75
Her mom comments that the waiter did a good job and deserves a 15% tip
Kallie notices that her mom leaves a $4 tip

So,

You can find $\:10\%$ by moving the decimal point one place to the left
$\:10\%$ of $18.75$ will be $1.875$ , then half of that will be $5\%$

So, $15\%$ should be be about $1.88\:+\:0.94\:=\:2.82$

Therefore, the tip was actually a little over 15% so we could surely say it is pretty sound and reasonable.

loris [4]

Answer

4800 ft3

Step-by-step explanation:

Formula for volume of a pyramid is 1/3*base*hight

because you do 20*20=400ft2 for the base

Then you times 36 (the hight) by 1/3 and get 12

Then you do 400*12=4800ft3 theres your answer
