Answer: Hello! The answer would be "8"
Step-by-step explanation:
When using the angle of 135 in each interior it would make a shape with 8 sides :)
The arcs in the corners of the triangle mean that all 3 angles are the same.
Because the 3 angles are all the same this means that all 3 sides are also the same.
To solve for X, we can set 2 of the equations to equal each other and solve for x:
6x-3 = 3x +6
Add 3 to each side:
6x = 3x +9
Subtract 3x from each side:
3x = 9
Divide both sides by 3:
x = 9/3
X = 3
And if you replace x with 3 in each of the equations, they all equal 15.
Answer:
Am = 1500 cm²
Step-by-step explanation:
If you mean leg around the right angle a = 3 cm and b = 5 cm then :
Formula for calculating area of the right triangle is:
A = a · b / 2 since we have 200 triangles, area of the mosaic is:
Am = 200 · A = 200 · a b / 2 = 200 · 3 · 5 / 2 = 1500 cm²
Am = 1500 cm²
God with you!!!
Answer:
8
Step-by-step explanation:
We are dealing with similaraty and similar shapes length are in proportion so we are going to set up an proportion.
Length of left triangle small side/ Length of left triangle long side= length of right triangle small side/length of right triangle long side
4/10=x/20
Cross multiply: 10x=80
x=8
Answer:
=0.00015241579
Step-by-step explanation:
Use the formula for geometric sequences:
=
Substitute 1 in for , -1/3 in for r, and 9 in for n
=(1)(-1/3^9-1)
=(1)(-1/3^8)
=(1)(0.00015241579)
=0.00015241579
Hope this helps! :)
