What is the measure of

Kamila [148]

Answer:

64.4

Step-by-step explanation:

In one of the trig formulas, it states sin <a/A = sin<b/B = sin<c/C

So we have in this case:

sin(70)/12 = sin x/14 Note: x is just a variable for the angle <ABC

14(sin70)/12 = sin x

sin^-1(14(sin70)/12) = x

x=64.4

Your welcome, and comment if you have any questions! :D

What is 585.30 rounded to the nearest whole number please HURRY

Bogdan [553]

If the first number behind the decimal point is lower than five, you leave the digits in front of the decimal the same. If it is equal to or above five, then the number in front of the decimal is rounded up. In this case it would stay the same, so your answer would be 585.

What is the slope of a line perpendicular to the line with equation 2x+3y=9

zheka24 [161]

Answer:

<h2> $slope = \frac{3}{2} \\$ </h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the slope of the perpendicular line we must first find the slope of the original line

The original line is

2x + 3y = 9

3y = - 2x + 9

$y = - \frac{2}{3} x + \frac{9}{ 3} \\ \\ y = - \frac{2}{3} x + 3$

Since the lines are perpendicular to each other the slope of the perpendicular line is the negative inverse of the original line

So the slope of the perpendicular line is

$slope = \frac{3}{2} \\$

Hope this helps you
