How many lines of symmetry does the figure have?<br><br><br> Which letter has rotational symmetry ?
Hunter-Best [27]

Problem 2

The figure has one line of symmetry.

This line is vertical and passes through the direct center. Imagine folding one side to have it land perfectly on the other side.

================================

Problem 3

The letter Z has rotational symmetry.

If we were to look at the letter, close our eyes, and then rotate it 180 degrees (or have a friend do so), we wouldn't see any difference if we opened our eyes again. The "before" and "after" images being identical is what gives it rotational symmetry. Put another way, rotating the letter 180 degrees has it line up with itself.

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 :)
