Answer:
Board 1 = 1.2m
Board 2 = 2.4m
Board 3 = 3.6m
Step-by-step explanation:
Board 1 = x
Board 2 = 2x
Board 3 = 3x
x + 2x + 3x = 6x
7.2 /6 = 1.2
Board 1 = 1.2
Board 2 = 2 (1.2) = 2.4
Board 3 = 3 (1.2) = 3.6
A pentagon is a closed 5 sided polygon.
A regular polygon has all sides equal as well as all angles equal.
°The formula to find the sum of all angles of a polygon is = (n-2) ×180
So for a pentagon, n= 5
So the sum of all the angles must be (5-2)× 180= 3 × 180 = 540.
Now as it is a pentagon, it shall have 5 vertices.
So there are 5 angles in a pentagon and all must be equal.
Hence each interior angle must be 540/5 = 108
So for a regular polygon with 5 sides must have each interior angle = 108
3/4x4=3 therefore she needs 3 cups of flour to make four batches of cookies : )
Answer:
Step-by-step explanation:
z has the value of 106 degrees the same as the other vertical angle
x =12
13x-82 +106 = 180
13x +24=180
13x= 156
x=12
13*12-82 +106 = 180
156-82+106=180
180=180

c^0.5
so 0.5=1/2 and if you have
x^(z/t)=
![\sqrt[t]{x^z}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bt%5D%7Bx%5Ez%7D%20)
so
c^1/2=
![\sqrt[2]{c^1} or \sqrt{c}](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7Bc%5E1%7D%20or%20%20%5Csqrt%7Bc%7D%20%20)
so
