A right triangle (triangle 1) has a hypotenuse length of 115 mm and α = 31.2°. What are the measurements for a, b, and β? 2. A r
kirza4 [7]

Alright, lets get started.

A right triangle (triangle 1) has a hypotenuse length of 115 mm and α = 31.2°. What are the measurements for a, b, and β?

Please refer the diagram I have attached.

Using SOH CAH TOA,

sin 31.2 = \frac{b}{115}

b = 115 sin31.2

Plugging the value of sin 31.2

b = 115*0.518 = 59.57 mm

Similarly,

cos31.2 = \frac{a}{115}

a = 115cos31.2

Plugging the value of cos 31.2

a = 115*.8553 = 98.36 mm

Now, for angle β

tan β = \frac{98.36}{59.57}

tan β = 1.65

Using tan inverse

β = 58.78°

So, the answer is a = 98.36 mm, b = 59.57 mm and β = 58.78°   :   Answer

Hope it will help :)

A right triangle (triangle 1) has measurements of a = 505 mm and b = 286 mm. What are the measurements for c, α, and β?

Please refer the diagram I have attahced.

a and b are given, we could side c by using Pythagorean theorem.

c^2 = a^2 +b^2

c^2 = 505^2 + 286^2

c^2 = 255025+81796

c^2 = 336821

Taking square root on both sides

c = 580.36 mm

Using SOH CAH TOA,

tan α = \frac{505}{286}

taking tan inverse

α = 60.48°

Similarly,

tan β = \frac{286}{505}

taking tan inverse

β = 29.52°

So, the answer is c = 580.36 mm, α = 60.48° and β = 29.52°   :    Answer

Hope it will help :)

Please give me the correct answer.Only answer if you're very good at math.Please don't put a link to a website.​
Alexus [3.1K]

Answer:

3, 50, 2

Step-by-step explanation:

By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.

3(n +25)= 5(10) +5(\frac{2}{5} n)

3(n +25)= 50 +2n

To find the value of n, expand the bracket on the left hand side:

3(n) +3(25)= 50 +2n

3n +75= 50 +2n

Bring all n terms to one side, constants to the other:

3n -2n= 50 -75

n= -25

Determine whether the triangles are similar. If there is sufficient information to determine that the triangles are similar, wri
schepotkina [342]

Answer: The triangles are similar. They are actually exactly the same.

Step-by-step explanation: (Statement) The reason I know these triangles are similar is because I flipped one up and realized they matched just opposite each other. Then I matched them up they were exactly the same
