Find the value of x and y in each triangle
Answers
The value of variables are,
⇒ x = 13.85
⇒ y = 16
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Base of triangle = 8
Now, We get;
⇒ cos 60° = 8 / y
⇒ 1/2 = 8/y
⇒ y = 8 × 2
⇒ y = 16
And, By Pythagoras theorem we get;
⇒ x² + 8² = y²
⇒ x² + 8² = 16²
⇒ x² + 64 = 256
⇒ x² = 256 - 64
⇒ x² = 192
⇒ x = √192
⇒ x = 13.85
Thus, The value of variables are,
⇒ x = 13.85
⇒ y = 16

Answer:
2000
Step-by-step explanation:
If 3 days = 600 we need to know what 1 day is so we do 600 / 3
600 / 3 = 200
Then multiply 200 by 10 to find 10 days
200 * 10 = 2000
10 days = 2000

Answer:
B. a = rⁿ
C. a¹/ⁿ = r
Step-by-step explanation:
ⁿ√a = r
The above expression can be simplified as follow:
1. ⁿ√a = r
Recall:
ⁿ√a = a¹/ⁿ
Therefore,
a¹/ⁿ = r
2. ⁿ√a = r
Take the n square of both side
(ⁿ√a)ⁿ = rⁿ
(a¹/ⁿ)ⁿ = rⁿ
a = rⁿ

Answer:
Length of arc = 14.13
Step-by-step explanation:
Given:
Radius of circle, r = 5
An arc in the circle has a central angle of 162°
To find the length of the arc, L, let's use the formula:
Where = 162°
Therefore, substituting figures, we have:
L = 31.4 * 0.45
L = 14.13
Length of arc is 14.13 units
