Answer:

x = 29

(x + 3)° = 32°

(x - 1)° = 28°

(x + 1)° = 30°

Step-by-step explanation:

(x + 3)° + (x - 1)° + (x + 1)° = 90°

-> (x + x + x +3 -1 + 1)° = 90°

-> (3x + 3)° = 90°

-> 3x + 3= 90

-> 3x = 90 - 3

-> 3x = 87

-> x = 87/3

-> x = 29

-> (x + 3)° = (29 + 3)° = 32°

-> (x - 1)° = (29 - 1)° = 28°

-> (x + 1)° = (29 + 1)° = 30°

Answer:

x=29

Step-by-step explanation:

The square notation indicates 90 degrees.

90=(x+3)+(x-1)+(x+1)

90=3x+3

87=3x

x=29

Total power generated by wind worldwide doubles every 3 years. In a particular year, the world wind-generating capacity was abou

NeTakaya

This is a problem of doubling time, the general formula for doubling time is

N = A(2)^( t /d)
where N is the future wind generating capacity in thousand MW
A is the initial wind generating capacity which is 95,000 MW
d is the time it will double, which is 3 years
t is the time in the future in years

N = 95(2)^( t / 3) is the formula for t<span>he continuous growth rate and give a formula for wind generating capacity W W (in thousand megawatts) as a function of t t , the number of years in the future</span>

Evaluate : 5-3(x-1) when x=7

Andrei [34K]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{ - 13}}}}$ </h3>

Step-by-step explanation:

Given , x = 7

let's find :

$\sf{5 - 3(x - 1)}$

Plug the value of x

⇒ $\sf{5 - 3(7 - 1)}$

Subtract 1 from 7

⇒ $\sf{5 - 3 \times 6}$

Multiply the numbers

⇒ $\sf{5 - 18}$

Calculate

⇒ $\sf{ - 13}$

Hope I helped!

Best regards!!

Linear pair angles are

guajiro [1.7K]

Answer:

Step-by-step explanation:

Linear Pair Angles are always congruent because you can see that the parallel lines are cut by a transversal, which creates special angle pairs. The angles would be Alternate Exterior Angles; angles on opposite sides of a transversal but outside the two parallel lines form supplementary angle pairs. The angles also are Corresponding Angles.
