Angles of a triangle add up to 180 degrees and then we take away the right angle
180-90=90
5x+5x=10x
90/10=9
x=9
Answer:
42
Step-by-step explanation:
Answer:
Rephrase that so that x=the number.
3+2x=x
(-2x) => 3=-x
(*-1) => -3=x
Therefore the number is -3!
Step-by-step explanation:
hope this helps :)
Answer:
2
Step-by-step explanation:
When given a fractional power, you want to try to see if the base has any power that can be used to simplify the power.
Since a^b/c =
![\sqrt[b]{ {a}^{c} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Bb%5D%7B%20%7Ba%7D%5E%7Bc%7D%20%7D%20)
8^1/3=
![\sqrt[3]{ {8}^{1} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%7B8%7D%5E%7B1%7D%20%7D%20)
8 times by it self it 8
cube root of 8 is three numbers that are the same and times by each other to give 8
2×2×2=8

The length of arc HK is 30.8 units
<h3>What is the length of arc?</h3>
The length of the arc is defined as the distance between two points on the arc on the circumference.
Length of arc = θ/360 x 2πr
where, r is the radius of arc and θ is the angle formed by the arc at the center.
Given, circle J with ∠HJK = 126° and HJ = 14 units'
Plug, the values, we get
length of arc = 126°/360° x 2π x 14 units
length of arc = 30.8 units
Thus, the length of arc HK is 30.8 units.
