Find the value of sin² R
1 answer:
If the hypotenuse of PQR triangle is 5 and perpendicular is ,then value of sin²R is 2/25.
Given that the hypotenuse is 5 and perpendicular is .
We are required to find the value of sin²R.
Trigonometric ratios are basically the ratios of the sides of the right angled triangle.
Sin is the ratio of perpendicular and hypotenuse of the right angled triangle. We can easily find the value of sin²R with the help of ratio of perpendicular and hypotenuse.
sin R=PQ/PR
sin R=/5
Squaring both sides,
sin² R=/
sin²R=2/25
Hence if the hypotenuse is 5 and perpendicular is ,then value of sin²R is 2/25.

Answer:
approximately 6.708 feet
Step-by-step explanation:
We use the Pythagorean theorem to solve the problem, using 3 feet and 6 feet as the legs of a right angle triangle. The diagonal of the screen is therefore the "hypotenuse" of this right angle triangle, and can be determined via the formula:
which is approximately 6.708 feet
Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3 Substitute the values
y – 5 = 3(x - 4) Remove parentheses
y – 5 = 3x - 12 Add 5 to each side
y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
