A right triangle is shown below.

Norma-Jean [14]

<h2>Answer: <em>x = 7.5</em></h2>

<em />

Step-by-step explanation:

Use the Pythagorean Theorem ( $a^{2}+b^{2} =c^{2}$ )

The longest side is <em>c = the hypotenuse</em>, and <em>a and b = the other sides</em> of the triangle.

a = 4 First: $4^{2}+x^{2}=8.5^{2}$

b = x Second: $16+x^{2}=72.25$

c = 8.5 Third: $x^{2}=56.25$

Fourth: $x=\sqrt{56.25}$

Fifth: x = 7.5

Using the diagram below, solve the right triangle. Round angle measures to the

olga nikolaevna [1]

Answer:

m∠A = 17 degrees m∠B = 73 degrees m∠C = 90 (given) a = 12 (given) b = 40 c = 42 (given)

Step-by-step explanation:

Use sin to solve m∠A

sin x = 12/42 Simplify

sin x = 0.2857 Use the negative sin to solve for x

sin^-1 x = 17 degrees

Add together all of the angle measures to solve for m∠B

17 + 90 + x = 180 Add

107 + x = 180

-107 -107

x = 73 degrees

Use Pythagorean Theorem to solve for b

12^2 + x^2 = 42^2 Simplify

144 + x^2 = 1764

-144 -144

x^2 = 1620 Take the square root of both sides

x = 40
