Answer:
1820
Step-by-step explanation:
The sum of the first n terms of a geometric series with common ratio r and first term a is:
a(1-r^n)/(1-r). Plugging this in 5(1-3^6)/(1-3)=1820
If two sides of one triangle are congruent to two sides of another triangle then CPCTC makes it SSS
Answer:
z=4
Step-by-step explanation:
If z=x/y and x=10 and y=2.5 then,
z=10/2.5
10/2.5=4
Answer:
x=45
Step-by-step explanation:
2x+45+x=180 since it is on a straight line
3x+45=180
3x=135
x= 45
x+4=3x
first subtract x from both sides(x-x and 3x-x)
4=2x
Now divide 2 from both sides (2x/2 and 4/2)
2=x
So x=2
