Step-by-step explanation:

Hello, there!!!

Let ABC be a Right angled triangle, 

where, AB = 3

BC= 10

and AC= x

now,

As the triangle is a Right angled triangle, taking angle C asrefrence angle. we get,

 h= AC = x

p= AB = 3

b= BC= 10

now, by Pythagoras relation we get, 

 $h = \sqrt{ {p}^{2} + {b}^{2} }$ 

 $or ,\: h = \sqrt{ {3}^{2} + {10}^{2} }$ 

by simplifying it we get, 

h = 10.44030

Therefore, the answer is x= 10.

Hope it helps...

4. Which of the following inequalities is true? A. 3 4 5 9 < B. 17 20 4 5 > C. 5 6 11 14 < D. 7 12 16 25

stellarik [79]

D. The true inequality is 7 < 12 < 16 < 25.

<h3>What is inequality?</h3>

Inequality is a statement of an order relationship including;

greater than,
greater than and equal to,
less than, or
less than and equal to

expressed between two numbers or algebraic expressions.

From the given options;

A. 3 > 4 < 5 < 9, this is not true since 3 is not greater than 4.

B. 17 < 20 < 4 < 5, this is not true since 20 is not less than 4.

C. 5 < 6 < 11 > 14, this is not true since, 11 is not greater than 14

D. 7 < 12 < 16 < 25, this is true, because 7 is less than 12 which is less than 16 and also less than 25

Thus, the option that contains the true statement of the inequalities is D.

The legs of a right triangle are 3 and 4 inches long how long is the hypotenuse

nataly862011 [7]

In the right angled triangle, a hypotenuse is the longest line of the triangle and is always the one that is opposite the right-angle of the triangle.
If your triangle is a right angled triangle, the simplest way is to use the Pythagora's Theorem to find the length of the hypotenuse. The formula for which is
a² + b² = c² where c is the unknown hypotenuse and a and b are the other two sides.
Using this formula,
3² + 4² = c²
9 + 16 = c²
25 = c²
√25 = √c²
5 = c which if you notice is also the lengthiest .

The price of a watch was increased by 20% to £144. What was the price before the increase?

hammer [34]

Answer:

120 pounds

Step-by-step explanation:

Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:

$\frac{144}{x}=\frac{120}{100}$
