Find the value of 0 round to the nearest whole degree

Mathematics
1 answer:
Jlenok [28]2 years ago
4 0

Answer:

27°

Step-by-step explanation:

we have the 'opposite' as length 2 is opposite the angle θ

we have the adjacent (length 4) which is next to the angle θ

the hypotenuse is the longest side (we don't need)

Using SOHCAHTOA

we use TOA as O is opposite and A is adjacent

tanθ = opposite ÷ adjacent

tanθ = 2 ÷ 4

using the inverse sign to find θ

θ = tan⁻¹(2/4) = 27° (to the nearest whole degree)

sergey [27]
Perpendicular lines have slopes that are negative reciprocals of one another.

slope intercept form (y = mx + b) of the first equation will help us find the slope of the first line: where m = slope

5x-4y=10
-4y=-5x + 10
y=-5/-4 x + 10/-4
y=5/4 x -2.5

if the slope of this line is 5/4 then the slope of the perpendicular line is -4/5.

Therefore with the given information we can state the equation of the second line in point slope form (y-y,) = m(x-x,)

the coordinates of (5,12) can are substituted for x, and y,

so the answer is

(y-12) = -4/5(x-5)

I hope this helped and is BRAINLIEST!

Good luck with your studies!

What is the ratio a:b if 8a=3b?
Digiron [165]

The ratio a:b is 3:8

Step-by-step explanation:

In simple words, the ratio a:b means the fraction a/b.

So we will have to solve the given equation for a/b

Given

8a=3b

Dividing both sides by 8

\frac{8a}{8}=\frac{3b}{8}\\a=\frac{3b}{8}

Dividing both sides by b

\frac{a}{b}=\frac{3b}{8*b}\\\frac{a}{b} =\frac{3}{8}

The ratio a:b is 3:8
