Answer:

11x - 1

Step-by-step explanation:

Just simplify the terms!

3x * 2 + 5x - 1

6x + 5x - 1 (We multiply 3x * 2 to get 6x)

11x - 1 (Then after that, all you have to do is add 6x and 5x together. We can't simplify further since we don't know what <em>x</em> is)

take x degree as reference angle

using tan rule

tan x=opposite/adjacent

tan x=6.1/5.1

tan x=1.19

x= $tan^{-1}$ 1.19

x=49.95

x=50 degree

M 2 = 2x°, m 3 = 5x°, m 1 =<br><br> 2x + 5x<br> 5x - 2x<br> 180 - 5x<br> 180 - 7x

MaRussiya [10]

We know: the sum of measures of triangle angles is 180°.

Therefore we have the equation

$m\angle1+m\angle2+m\angle3=180^o\to m\angle1=180^o-m\angle2-m\angle3$

Substitute $m\angle2=2x,\ m\angle3=5x$ :

$m\angle1=180-2x-5x=180-7x$

<h3>Answer: 180 - 7x</h3>

a recipe called for 2 cups or liquid, which includes 1/4 cups molasses. What fraction of the liquid in the recipe is molasses?

AlladinOne [14]

1 3/4 of the cup will be the other liquid because if you take 1/4 from 2, that would be 1 3/4.
