The measures of the angles of a triangle are shown in the figure below. Solve for x.

tino4ka555 [31]

Answer:

The vale of x=4

Step-by-step explanation:

We know that the sum of angles of a triangle = 180°

Given

(3x+13)

(8x+14)

109°

Thus, the equation becomes

(3x+13) + (8x+14) + 109° = 180°

11x + 27 + 109° = 180°

11x = 180°- 109° - 27

11x = 44

x = 4

Thus, the vale of x=4

What is the width of a rectangle with a length of 14 cm and an area of 161 cm squared

mestny [16]

Area of a rectangle=length×width. If the area is 161 and the length is 14 then that means: 161=14×width. You would then divide 161÷14 and you will find that the width is 11.5.

if trapezium of area 140 cm horsepower sides 10 cm apart and one of them decides is 16 cm longfind the area find the length of t

Vilka [71]

Given :

Area of the trapezium is 140 cm².
Its height is 10 cm.
One of the parallel side is 16 cm.

To Find :

The other parallel side.

Solution :

Let the other parallel side be x

We know that,

${ \qquad \: \pmb{ \dfrac{1}{2} \times (sum \: of \: the \: parallel \: sides) \times height} = \pmb{Area_{(trapezium)}}}$

Now, Substituting the given values in the formula :

$\qquad { \dashrightarrow \: { \sf{ \dfrac{1}{2} \times (16 + x)\: \times 10 \: = {140}}}}$

$\qquad { \dashrightarrow \: { \sf{ 5 \times (16 + x)\ \: = {140}}}}$

$\qquad { \dashrightarrow \: { \sf{ 80 + 5x = {140}}}}$

$\qquad { \dashrightarrow \: { \sf{ 5x = {140 - 80}}}}$

$\qquad { \dashrightarrow \: { \sf{ 5x = {60}}}}$

$\qquad { \dashrightarrow \: { \sf{ x = { \dfrac{60}{5} }}}}$

$\qquad { \dashrightarrow \: { \pmb{ x = { 12 }}}}$

Therefore,

The other parallel side of the trapezium is 12 cm.
