Can a right triangle have a leg that is 10 meters long and a hypotenuse that is 10 meters long
pishuonlain [190]
Lets see
a and b are legs
c=hypotnuse
a^2+b^2=c^2
10^2+b^2=10^2
100+b^2=100
minus 100 both sides
b^2=0
b=0
false, if you have a leg legnth 0, then they lines are right on top of each other

Helppppppppppppppppppppppppppppppppppppppppppp meeeeee
Zigmanuir [339]

Answer:

Angle A = 19

Step-by-step explanation:

Vertical angles are congruent ( equal to each other )

If angle A and angle B are vertical angles and vertical angles are congruent then angle A = angle B

If angle A = 3x + 13 and angle B = 5x + 9 then 3x + 13 = 5x + 9

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

3x + 13 = 5x + 9

Step 1 subtract 3x from both sides

Outcome: 13 = 2x + 9

Step 2 subtract 9 from both sides

Outcome: 4 = 2x

Step 3 divide both sides by 2

Outcome: x = 2

Now to find Angle A

All we have to do to find the measure of angle a is simply substitute 2 for x in it's given expression ( 3x + 13 )

Substitute 2 for x

Angle A = 3(2) + 13

Multiply

Angle A = 6 + 13

Add

Angle a = 19

The oxygen levels in parts per million and altitude in x miles at Mt. Everest decrease according to the function: 0 (x)= 100(.95
CaHeK987 [17]

Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.

<h3>What is the exponential function for the oxygen levels?</h3>

The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:

O(x) = 100(0.95)^x

In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:

O(10) = 100(0.95)^{10} = 59.87
