Answer:

Step-by-step explanation:

All of the angles are marked as congruent, which means it is an equlateral triangle. This means that all of the sides are congruent too.

Therefore z + 2 = 2z -10

add 10 to each side

z + 12 = 2z

subtract z from each side

12=z

now that we know that, we can plug it back in to either line (it doesn't matter because they're congruent)

line AB is z+2 which is 12+2 or 14

and line CB is 2z-10 which is 2(12)-10 or 24-10 which is also 14

so line CA is also 14 units long.

At Php14.75 per plastic bag of charcoal, how many bags can be bought with P132.75

matrenka [14]

<u>9 bags</u> can be brought

Explanation :-

As per given conditions,

$\frac{132.75}{14.75}$

Multiplying numerator and denominator to get positive values,

$\frac{132.75 \times 100}{14.75 \times 100}$

$= > \frac{13275}{1475}$

Now by normal division, we get,

luda_lava [24]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The width of the room is 30 meters.

If two beams will be making an angle, they will half the width.

There will be a right triangle made, so using SOH CAH TOA,

$cos x=\frac{adjacent}{hypotenuse}$

$cos x=\frac{15}{17}$

taking cos inverse

x = $cos^{-1} (\frac{15}{17} )$

x = 28.07° : Answer

Hope it will help :)

Using the measure of x. What is the measure of ∠AMB?

lawyer [7]

Answer:

∠AMB = 54°
