The length and width of a rectangle are measured as 30cm and 24cm, respectively, with an error in measured of
at most 0.1cm in each. Use differentials to estimate the maximum error in the calculated area of rectangle.

n

step-by-step explanation:

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
