Which is the right triangle

Answers

Answer 1

Answer:

Using the pythagorean theorem

A) $(√(2))^(2) + (√(3))^(2) = (√(4))^(2)$

2 + 3 = 4

5 = 4

since 5 is not equal to 4 so A is wrong

B) $(√(8))^(2) + (3)^(2) = (√(17))^(2)$

8 + 9 = 17

17 = 17

so answer B) is correct

C) $(5)^(2) + (6)^(2) = (8)^(2)$

25 + 36 = 64

61 = 64

since 61 is not equal to 64 so C) is also wrong

A giraffe is standing 22 feet from a naturalist hiding in the bush. The naturalist sights the animal and finds the angle of elevation is 30 degrees How tall is the giraffe?

Answers

Answer:

height = 12.7 feet

Step-by-step explanation:

To find the height of the giraffe, we just need to use the tangent relation of the angle of elevation.

The opposite side to the angle is the height of the giraffe, and the adjacent side of the angle is the distance between the giraffe and the narutalist.

So, we have that:

tangent(30) = height / distance

0.5774 = height / 22

height = 22 * 0.5774 = 12.7 feet

Answer:

12.7

Malik stops at the grocery store to buy a bag of diapers and 2 cans of formula. He spends a total of $37. The next week he stops and buys 2 bags of diapers and 5 cans of formula for a total of $87. How much does a bag of diapers cost? How much is one can of formula?

Answers

Answer:

Diapers costs $11 and formula is $13.

Step-by-step explanation:

Let's name diapers as A and formula as B.

Simply the equations:

1A + 2B = $37(1)

2A + 5B = $87(2)

Clear D from one equation.

A = $37 - 2B(1)

Replace D into the other equation.

2*($37 - 2B) + 5B = $87(2)

$74 - 4B + 5B = $87

$74 + B = $87

B = $87 - $74 = $13

Find A, now knowing B.

A = $37 - 2($13)

A = $37 - $26 = $11

Answer:

Cost of a bag of diapers is $11 and cost of one can of formula is $13.

Step-by-step explanation:

Let cost of each diaper = $D and cost of each cans of formula = $C

Malik shops a bag of diapers and 2 cans of formula.

He spends total of $37.

So the equation will be

D + 2C = 37 -------(1)

Next week he stops and buys 2 bags of diapers and 5 cans of formula.

He spends total $87.

Equation for this purchase will be

2D + 5C = 87 ----------(2)

Multiply equation (1) by 2 and subtract it from equation (2).

2(D + 2C) - (2D + 5C) = 2×37 - 87

2D + 4C - 2D - 5C = 74 - 87

-C = - 13

C = 13

From equation (1)

D + 2×13 = 37

D + 26 = 37

D = 37 - 26

D = 11

Therefore, cost of a bag of diapers is $11 and cost of one can of formula is $13.
