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 :)

Find the standard form of the complex number 6(cos(30degree) +i sin (30 degree))
Marat540 [252]

Answer:

= 3√3 + 3i

Step-by-step explanation:

Cos 30° = √3/2

Sin 30°  = 1/2

Therefore;

z = 6 (cos 30° + i6 sin 30°)

  = 6 (√3/2) + i 6 (1/2)

   = 3√3 + 3i

Answer:

100°

Step-by-step explanation:

two angles are supplement .

if their sum is equal to 180°

supplement angle of  80° + x = 180°
