What is the smaller angle of (x+20) (5x+10)

Step-by-step explanation:

Angle measure of the smaller angle in two complement angles = x

Angle measure of the bigger angle = x + 20

Their sum = 90° ( the sum of two complementary angles is always equal to 90° )

This can be written in an equation as =

= x + x + 20 = 90

= 2x + 20 = 90

= 2x = 90 - 20 ( transposing +20 from LHS to RHS changes +20 to -20 )

= 2x = 70

= x = 70 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )

= x = 35

Then the value of the smaller angle = x = 35°

The value of the bigger angle = x + 20 = 35 + 20 = 55°

Therefore , the measure of degrees in the the smaller angle is :

Angle measure of the smaller angle in two complement angles = x

Angle measure of the bigger angle = x + 20

Their sum = 90° ( the sum of two complementary angles is always equal to 90° )

This can be written in an equation as =

= x + x + 20 = 90

= 2x + 20 = 90

= 2x = 90 - 20 ( transposing +20 from LHS to RHS changes +20 to -20 )

= 2x = 70

= x = 70 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )

= x = 35

Then the value of the smaller angle = x = 35°

The value of the bigger angle = x + 20 = 35 + 20 = 55°

Therefore , the measure of degrees in the the smaller angle is :

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
