scoray [572]3 years ago
4 0

Step-by-step explanation:

tan 60 = 21 ÷ y

1.73 = 21 ÷ y

y = 21 ÷ 1.73

y = 12.14

tan 30 = x÷ 12

0.6 x 12 = x

x = 7.2

In 2013, the world’s total output (real gdp) was roughly $73 trillion. what percentage of this total was produced:
KiRa [710]
The GDO these 3 countries respectively are $ 16.8 trillion, $ 9.2 trillion and $ 4,9 trillion. so the sum of the GDPGDP total = 16.8 + 9.2 + 4.9= 30.9
hence the percentage of the total output of the 3 largest economies is as follows:percentage = ( total gdp / total output of the world ) x 100
percentage = ( 30.9 / 73 ) x 100percentage = 42.33 %

What is the equation of the line that passes through the point (2,-6)and has a slope of −1?
Alecsey [184]

Step-by-step explanation:

Hey there!!

Just simply work with it.

We know that we have to use one point formula to find the equation of a st.line passing through point and slope is given.

So, just do accordingly.

The point is (2,-6) and slope is -1.

(y - y1) = m(x - x1)

Where, "m" is a slope.

Put all values.

(y  + 6) =  - 1(x - 2)

Simplify them to get answer.

(y + 6) =  - x + 2

y =  - x - 4

Therefore the equation is y= -x-4 OR can be written as x+y+4=0.
