the legs of a right triangle measure 7 units and 24 units. what is the measure of the hypotenuse? round to the nearest tenth is

Travka [436]

The measure of the hypotenuse is 25.0 units

Step-by-step explanation:

Let us revise how to find the length of the hypotenuse in a right Δ

If the two legs of a right triangle are x and y
If the hypotenuse is z
According to Pythagoras Theorem $z=\sqrt{x^{2}+y^{2}}$

∵ The legs of a right triangle measure 7 units and 24 units

∴ x = 7 units and y = 24 units

∵ $z=\sqrt{x^{2}+y^{2}}$

- Substitute the values of x and y in the rule to find z

∵ $z=\sqrt{(7)^{2}+(24)^{2}}$

∴ $z=\sqrt{49+576}$

∴ $z=\sqrt{625}$

∴ z = 25 units

∵ z is the hypotenuse

∴ The measure of the hypotenuse = 25 units

The measure of the hypotenuse is 25.0 units

What is the constant in

Troyanec [42]

Answer:

Part a) $n=-8.017176$

Part b) $n=9.700465$

Step-by-step explanation:

Part a) we have

$9^{(n+10)}+3=81$

Solve for n

Subtract 3 both sides

$9^{(n+10)}+3-3=81-3$

$9^{(n+10)}=78$

take log both sides

$log[9^{(n+10)}]=log[78]$

$(n+10)log[9]=log[78]$

$(n+10)=log[78]/log[9]$

$n=\frac{log(78)}{log(9)}-10$ ----> using a calculator

$n=-8.017176$

Part b) we have

$11^{(n-8)}-5=54$

Solve for n

Adds 5 both sides

$11^{(n-8)}-5+5=54+5$

$11^{(n-8)}=59$

take log both sides

$log[11^{(n-8)}]=log[59]$

$(n-8)log[11]=log[59]$

$(n-8)=log[59]/log[11]$

$n=\frac{log(59)}{log(11)}+8$ ----> using a calculator

$n=9.700465$
