The first sixty digits of its decimal expansion are: 1.73205080756887729352744634150587236694280525381038062805580
the value of root 3 with three decimal places is 1.732
9 gallons of gasoline would cost 30.33
9 x 3.37=30.33 you just have to multiply the gas by the gallons and then that will give you your answer
Answer:
Step-by-step explanation:
Remark
A right triangle with one other angle = 45 degrees is isosceles (two sides are equal). So the bottom line of the square is also s
Formula
s^2 + s^2 = 20^2 Add the terms on the left. Square the right.
Solution
2s^2 = 400 Divide by 2
2s^2/2 = 400/2 Simplify
s^2 = 200 Take the square root of both sides.
Answer
sqrt(s^2) = sqrt(200)
s = 14.1 or s = 10*sqrt(2)
The indicated side of the right triangle is .
<h3>RIGHT TRIANGLE</h3>
A triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says:. And the main trigonometric ratios are:
The question asks to find one of the legs (y). Then, you can find y applying the trigonometric ratio (sin 45°).
Like sin45° is equal to , you have

Step-by-step explanation:
x+100°=180°{being straight angle}
x=180-100
x=80°
again,
45°+x+y=180°{sum of angle of triangle}
45+80+y=180
y=180-125°
y=55°
hope it helps.
