im pretty sure you dont need exponents for this bud
3x-x-4x+4x
2x+0
2x
Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°
The one and only answer is b
The explicit formula is an= 4.2*
.
The correct option is (b)
<h3>What is explicit formula?</h3>
The explicit formula for a geometric sequence is of the form an = a1r-1, where r is the common ratio.
Given sequence: {4.2, 3.57, 3.0345, 2.5793, …}
General formula 
an=4.2* 
an= 4.2* 
Hence, an= 4.2*

The answer is D
if the legs are 5 and 4 cm the equation to find the hypotenuse would be 5^2+4^2=c^c
5 squared is 25 and 4 squared is 16 that gives you 41, normally you would square root the 41 but it gives you a decimal number
