Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

3x + 12 + 54 + 90 = 180, simplify

3x + 156 = 180 ( subtract 156 from both sides )

3x = 24 ( divide both sides by 3 )

x = 8

Answer:

x = 8

Step-by-step explanation:

if the angle is equal to 36º that means (3x+12)º = 36º so simplify the equation and solve for x

3x+12 = 36

3x = 24

x = 8

Trees are planted at intervals of 5 m along side of a 140 m straight path. The first tree is planted at the start of the path an
Luden [163]
<h3>Solution :</h3>

Distance between first tree and last tree is 140m .

And distance between each tree (d) = 5 m

let's solve for number of trees (n) :

\hookrightarrow \: (n - 1)d = 140

\hookrightarrow \: (n - 1)5 = 140

\hookrightarrow \: n - 1 =  \dfrac{140}{5}

\hookrightarrow \: n = 28 + 1

\hookrightarrow \: n = 29

hence, total number of trees = 29.
