Suppose the hypotenuse of a right triangle is 24 cm and one of the legs is 11 cm. Use the Pythagorean Theorem to find the measur
uysha [10]

Answer:

The answer is number 4. 21.3 cm

Step-by-step explanation:

In the picture you can see the draw of the triangle and the formula of the Pythagorean Theorem.

We substitute the values in the Pythagorean Theorem

c² = a² + b²

We clear the equation for b

b² = c² - a²

b² = (24)² - (11)²

b² = 576 - 121

b² = 455

√b² = √455

b = 22.3 cm

Saul made some extra money last year from a part-time job. He invested part of the money at 2% with four times as much invested
omeli [17]

Answer:

$4000

Step-by-step explanation:

Given that :

Total interest earned = $150

Let amount invested (p) at 2% = x

Amount invested (p) at 3.25% = 4x

Interest = principal * rate * time

At 2%:

(x * 0.02 * 1 ) + (4x * 0.0325 * 1) = 150

0.02x + 0.13x = 150

0.15x = 150

x = 150 / 0.15

x = 1000

Hence,

Amount invested at 2% = x = 1000

Amount invested at 3.25% = 4x = 4(1000) = 4000

An isosceles triangle has slant height s and angle t opposite the base. Find a formula for the base length b in terms of the ang
Mars2501 [29]

OK, let's try with no figure.  We have an isosceles triangle sides s,s, and b.

Opposite b is angle t.

Draw the altitude h to bisect t.  We have two right triangles, legs b/2 and h, hypotenuse s.  The angle opposite b/2 is t/2 so

sin(t/2) = (b/2)/s = b/2s

So we arrived at the first part,

b = 2s sin(t/2)

The area of a triangle with sides s,s and included angle t is

A = (1/2) s² sin t
