Question

Can you do this this is my challenge

Answer 1

HEY MATE HERE'S YOUR ANSWER !!!

9. Let the smallest number two numbers be x. thus, we have the two numbers as x and 10+x.
given that, sum of the two numbers = 40
so, x + 10+x = 40
=> 2x +10 = 40
=> 2x = 30
=> x = 15
hence, the two numbers are 15 and 25.

10. We know that,
sum of all the angles in a quadrilateral is always 360°.
let the measure of fourth angle of the quadrilateral be x°.
then, 65°+ 115° + 60° + x° = 360°
=> 230° + x° = 360°
=> x° = 20°
hence, the required fourth angle of the quadrilateral is 20°.

HOPE THIS HELPS YOU

HAVE A GREAT DAY

Answer 2

hii
second answer is as we know sum of angles of quadrilateral is 360
65 +115+60+x=360
x=120
fourth angle is 120
