Answer:
x=124.75
Step-by-step explanation:
Sum of angles of a triangle=180°
(x-40)+(x-20)+(1/2- 10)=180°
(x-40)+(x-20)+(−9.5)=180°
x-40+x-20−9.5=180°
x+x-40-20-9.5=180°
2x−69.5=180°
2x=180°+69.5
2x=249.5
2x/2=249.5/2
x=124.75

The first term of the geometric sequence is 0.0061
<u>Step-by-step explanation:</u>
The general form of geometric sequence is a, ar, ar²,ar³,.......
where,
- a is the first term of the sequence.
- r is the common ratio. Here, the common ratio r = 4.
- The 8th term of the sequence is 100. Hence n = 8.
<u>The formula to find the nth term of the geometric sequence is given by :</u>
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ a = 0.0061
Therefore, the first term of the geometric sequence is 0.0061

Answer: 1,626 cubic meters
Step-by-step explanation:
V= lwh
V= length x with x height
Each number isn't specified (i dont know which numbers represent the width, length, and height since it isn't said) but that doesn't matter because according to the commutative property , you can multiply in any order and still get the same result.
So V= 15.8 x 24.5 x 4.2
V= 1,625.82
Rounded to the nearest cubic meter: 1,626 because 1625.82 becomes 1625.8, which, to the nearest whole number, is 1,626.
