What is the third angle of a right triangle if one of the angles measures 51 degrees

2 answers:

4 0

All angles of a triangle add up to 180 degrees. If it's a right triangle, the right angle is 90 degrees. If another angle is 51 degrees then the last angle has to be 180 - 90 = 90 - 51 = 39 degrees.

Since it's a right triangle one angle will be 90°
■■■■■■■■■■■■■■■■■■■■
90°+51°=141°
A triangle is 180°
180°-141°=39°

THE THIRD ANGLE WILL BE 39°

Find the range of the function for the domain {−3, 1, 4.5}.

Nitella [24]

Answer:

D. {4, 0, -3.5}

Step-by-step explanation:

domain (x) = {-3, 1, 4.5}

y= -x + 1

substituting domain/x-values into y= -x + 1

x= -3

y = -(-3) + 1

= 3+1

= 4

x= 1

y = -(1) + 1

= 0

x = 4.5

y = - (4.5) + 1

= -3.5

therefore, range ={4, 0, -3.5}

Sarah has $400 in her bank account and she has to pay $15 each month to her parents for her cell phone bill. darius has $50 and

ELEN [110]

They will have the same amount of money after 10 months

They will have $250 at this point

Step-by-step explanation:

The given is:

Sarah has $400 in her bank account and she has to pay $15 each month to her parents for her cell phone bill
Darius has $50 and saves $20 each month from his job

We want to find when Sarah and Darius will have the same amount of money and how much they will have at this point

Assume that they will have the same amount of money in x months

∵ Sarah has $400 in her bank account

∵ She has to pay $15 each month to her parents for her cell phone bill

∵ She do that for x months

∴ Her amount of money = 400 - 15(x)

∴ Her amount of money = 400 - 15 x ⇒ (1)

∵ Darius has $50

∵ He saves $20 each month from his job

∵ He do that for x months

∴ His amount of money = 50 + 20(x)

∴ His amount of money = 50 + 20 x ⇒ (2)

∵ They have the same amount of money in x months

- Equate (1) and (2) to find the value of x

∴ 400 - 15 x = 50 + 20 x

- Subtract 50 from both sides

∴ 350 - 15 x = 20 x

- Add 15 x to both sides

∴ 350 = 35 x

- Divide both sides by 35

∴ 10 = x

They will have the same amount of money after 10 months

Substitute the value of x in (1) or (2) to find the amount of money they will have at this point

∵ The amount of money = 400 - 15(10)

∴ The amount of money = 400 - 150

∴ The amount of money = $250

They will have $250 at this point
