Perimeter = length of the 3 sides of the triangle ie 34units
Since width we are given 6.5 units
We have to find the remaining 2 sides:
Formula of Triangle for Perimeter
P = a + b + c (sum of sides)
simplify: P= a + 2b (its an isosceles)
34 = 6.5 + 2b
34 - 6.5 = 2b
27.5 = 2b
Só b = 13.75 units each length of triangle
Relationship between triangle and rectangle
= rectangle has four right angles, so a triangle has an angle of half since it bisects the edges (ie 45*)
Use Trig Ratios to find L
SOHCAHTOA
we want adjacent ( L)
13.75 sin 45
L = 9.72
Thus your equation is
Equation used to find Triangle × Trig ratios
P = a + 2b
sin 45
Where L is length of rectangle
a is width of triangle
L =(P - a +2b)× sin 45

Decimal Answer : 0.958763
Answer:
$420
Step-by-step explanation:
Given data
GIven ratio= 2:3
The total ratio= 2+5= 7
Ann's share= $120
Let us apply the part to all approach
let the total amount be x
so for Ann
2/7= 120/x
cross multiply
2x= 120*7
2x= 840
divide both sides by 2
x= 840/2
x= 420
Hence the amount shared is $420
Answer : 2.5
Step - by - step explanation :
X / Y = COP
5 / 2 = 2.5 or 2 1/2
Y = 2.5x
Answer:
- diagram is below
- 6, 11, 16, 21
- s[n] = s[n-1] +5
- 26, 31, 36
Step-by-step explanation:
a) See below for the next diagram in sequence.
__
b) The numbers of straws in each diagram are ...
6, 11, 16, 21, ...
__
c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...
s[1] = 6
s[n] = s[n-1] +5
__
d) The next three terms of the sequence are ...
..., 26, 31, 36, ...
