Wrong , actually the complement of an obtuse angle is a right angle

X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
<span>The correct answer is 1.
Explanation:
The way this is written, everything after the words "divided by" would be calculated first; it is written as though this is a grouping, such as 20/(2*(5+5)). We would evaluate the innermost parentheses first; 5+5=10. Then this gives us 2*10=20 in our parentheses. 20/20 = 1.</span>
Answer:
√2
Step-by-step explanation:
Angle ( θ ) = 45
Hypotenuse side = 2
Opposite side = x
Formula : -
sin θ = Opposite side / Hypotenuse side
Note :
The value of sin 45 = 1/√2
sin 45 = x/2
1/√2 = x/2
Cross multiply,
x*√2 = 2*1
x√2 = 2
2 can be simplified as √2 * √2
x√2 = √2*√2
Divide √2 on both sides,
x = √2
Answer:
phythaforean theorem:
1 . The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
2. Find the square root to find the accurate length of the hypotenuse.
distance formula:
1. The distance formula is used to determine the distance, d, between two points.
distance = speed × time
Formula- d= √x2-x1)²+(y2-y1)²
2. It's used for :
-Finding the perimeter of polygons
-Finding the area of rectangles
-Finding the equation of a circle
