Question

This is my homework please give the answer correctly .

I will mark you as brainliest.​

Answer 1

15. let the number is x

11x+12x= 120

23x= 120

x= 120/23= 5.2

11x= 11x5.2= 57.2

12x=12x5.2= 62.4

please mark me as brainlist

Answer 2

Answer:

q13.) Steps of construction (With respect to the figure in the attachment)

Draw a line segment AB

Take a compass and form a semi circle by taking A as centre

Now taking C as centre (With same compass opening) Form an arc on the semi circle (Mark as D)

Cut another arc by taking D as centre and label as E

Now make two arcs (By taking D and E as centre)

Mark the meeting point as F

Finally join A and F

Right Angle is ready

Bisecting it -

Make two arcs by taking F and C as centre and mark the meeting point as G

Finally join G and A

Right angle with its bisector is ready..

14) Steps of construction (With respect to the figure in attachment)

Form a line segment AB (8 cm) with the help of a ruler

Make a semi circle by taking A as centre

Now, by taking c as centre cut an arc on the semi circle (Label as D)

Now by taking D as centre cut another arc on the semi circle (Mark as E)

Join E and A

Angle of 120° is ready

Bisecting it -

Join A and D (Point D is of 60°) which will form the bisector of the angle of measure 120°.

15) Let nos. be 11x and 13x

Sum = 120

11x + 13x = 120

24x = 120

x = 120/24

x = 5

Nos. are = 5×11 = 55

and 5×13 = 65

Hope this helps uhh in ur hw
