Answer:

90 degree

Step-by-step explanation:

∠ 1 , ∠2 and ∠3 are three interior angles of a triangle so the sum of these three angles are 180°

From the figure, ∠1 is a right angle means m∠1=90°

m∠1+m∠2+m∠3=180°

m∠2+m∠3=180°-m∠1

m∠2+m∠3=180°-90°

m∠2+m∠3=90°

Answer:84

Step-by-step explanation:

Okay. Are you taking calc? Dv/dt =d/dt(L(t)^3)=d/dt[(sqrt(14)+2t)^3]= 6(Sqrt(14)+2t)^2)=44. We defined t=0 to be time at which length is sqrt(14). Does that work?

The number of men and women receiving​ bachelor's degrees each year has been steadily increasing. For the years 1970 through the
slega [8]

Answer:

Step-by-step explanation:

Given:

The number of men receiving degrees (in thousands)

y = 3.8x + 441

The number of women receiving degrees (in thousands)

y = 14.4x + 311

y = 14.4x + 311

y = 3.8x + 441

Solving the above equations simultaneously,

3.8x + 441 = 14.4x + 311

10.6x = 130

x = 12.24

Inputting the value of x into the initial equation to find y,

y = 3.8(12.26) + 441

= 487.6

Therefore, the point (12.26 , 487.6) will be the solution of our given equations.

The area of a rectangle is 256.5m.  If the length is 18m what is the perimeter of the rectangle?
irga5000 [103]
The area of a rectangle equals length times height. (A=LH)

A=256.5 L=18

Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)

next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.

So, it is 256.5/18 equaling H

256.5 divided by 18 is... 14.25

That means the height is 14.25 an the length is 18.

the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.

So you have two sides that are 14.25 and two that are 18 meters long.

14.25+14.25+18+18 equals the perimeter then.

So the answer would be... 64.5!
