I only need to know is it 360 or 180?
Sveta_85 [38]

Answer:

So we know that all angles add up to 360. We first subtract it by 81

Now we have 279 as an answer. But since 2w + 81 cant be 360 because it doesn't add up because you have to spaces in between them. It adds up to 180 not 360

<h2><u>From your question its 180</u></h2>

Find the area of parallelogram ABCD given m A = 30 and the following measures. AB = 6 ft.; AX = 3√3 A = ? A. 18 ft.² B. 18√3 ft.
S_A_V [24]

Answer:

Given that a parallelogram ABCD has sides AB= 6 ft and AX = 3√3

Angle A =30

To find the area of the parallelogram

We have area of parallelogram = base x height

Here base can be taken as side AB = 6 ft

Height = perpendicular distance of AB from vertex X

= AX sin A

= 3√3sin30

=1.5√3

Hence area =6(1.5√3)=9√3ft^2

Sandra is 4 feet tall. Pablo is 10% taller than Sandra and Michaels is 8% taller than Pablo. What is Michael height in feet
taurus [48]


We first calculate  Pablo's height .

4 = 100%

x = 1%  (Where x is 1% of  Sandra's height.)

cross multiplying the equation, we get:

100x = 4 →  x = 4/100  → x = 0.04

If 1% = 0.04, then 10%  will be 0.04 × 10 = 0.4

Pablo's height is 4 + 0.4 =  4.4 feet.

Now we repeat the above steps to get Michal's height from Pablo's height

4.4 = 100%

x =  1%       so:

100x = 4.4 → x = 4.4/ 100 → x = 0.044

If 1% = 0.044, then 8% will be 0.044 × 8 = 0.35

Michael's height is  4.4 + 0.35 = 4.75 feet.
