The hypotenuse of a right triangle is 6 inches. if one of the legs is 2 inches, find the degree measure of each angle
miskamm [114]
A and b are the 2 smaller sides, and c = hypotenus; only for right triangles,
Pythagorean Theorem states that:
{c}^{2}  =  {a}^{2}  +  {b}^{2}
given c = 6 in., a = 2 in.
{c}^{2}  =  {a}^{2}  +  {b}^{2}  \\  {6}^{2}  =  {2}^{2}  +  {b}^{2}  \\ {b}^{2} =  {6}^{2}  -  {2}^{2} = 36 - 4   \\ \sqrt{ {b}^{2} }  =  \sqrt{36 - 4}  =  \sqrt{32}
b =  \sqrt{32}   =  \sqrt{16}  \times  \sqrt{2}  = 4 \sqrt{2}  \\ b = 5.66 \: inches
So the three side are 2, 6, and 5.66 inches

Find the value of x in the triangle shown below.<br> a. x=21<br> b. x=42<br> c. x= 15<br> d. x=21
elena55 [62]

THEOREM:

  • <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

ANSWER:

By pythagorean property,

  • x² = 12² + 9²
  • x² = 144 + 81
  • x² = 225
  • x = √225
  • x = 15 units.

So, <u>Correct choice</u> - [C] 15 units.

I need help now please, I can’t figure this out
otez555 [7]

Answer:

B. 1,4

Step-by-step explanation:

1. substitute 4x for y in the second equation since we know y=4x(to find x)

6x-4(4x)=-10

2.solve for x

6x-4(4x)=-10

-4•4x=-16x

6x-16x=-10

6x-16x=-10x

-10x=-10

-10x/-10=-10/-10

x=1

3.substitute 1 for x in either equation(since x=1)to find y

y=4(1)

y=4

x,y=1,4

hope this helps!
