Answer:

c 75

Step-by-step explanation:

you dont have to do math for this

its an acute angle so a is wrong, but the angle is not small enough to be 25 degrees so d is not the answer, its not b either because 85, lemme just put a picture in

c is the correct answer

(the 1st photo is an 85 degree angle)

(the second is a 75 degree angle)

sorry if this is confusing

Answer: x = 75°

Steps:
180 - 155 = 25

80 + 25 + x = 180
105 + x = 180
x = 180 - 105
x = 75

Check:
80 + 25 + x = 180
80 + 25 + 75 = 180
180 = 180 ✅

I would appreciate the brainliest if this was helpful correct and had clear steps! :)

spayn [35]

Answer: There are 32 students who like brussels sprouts but dislike beans.

Step-by-step explanation:

Since we have given that

Number of students eat in the cafeteria = 120

Fraction dislike lime beans = $\dfrac{2}{3}$

Fraction who dislike lime beans and brussles sprouts both = $\dfrac{2}{3}\times \dfrac{3}{5}$

Fraction who dislikes lime beans but not brussles is given by

$\dfrac{2}{3}(1-\dfrac{3}{5})\\\\=\dfrac{2}{3}\times \dfrac{2}{5}\\\\=\dfrac{4}{15}$

So, Number of students who like brussels sprouts but dislike lima beans is given by

$\dfrac{4}{15}\times 120\\\\=32$

Hence, there are 32 students who like brussels sprouts but dislike beans.

Find the value of x in the figure.<br><br> X= _

natulia [17]

Answer:

x=35

Step-by-step explanation:

For a polygon with n sides, the sum of its interior angles is equal to

(n-2) * 180

Here, there are 6 sides, so the sum of this polygon's interior angles is equal to (6-2)* 180 = 720

Therefore, the sum of the interior angles is 720. We can add them up to get

(4x-5) + 117 + (3x-3) + (3x+6) + 118 + 4x-3

= 14x +230 = 720

subtract 230 from both sides to isolate the x and its coefficint

14x = 490

divide both sides by 14 to get x

x=35

Quadratic formula 3x^2 - 2x + 5 = 0

Tanzania [10]

Step-by-step explanation:

The given quadratic equation is :

$3x^2 - 2x + 5 = 0$

We need to solve the given equation. The formula used to solve a quadratic equation is :

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

We have, a = 3, b = -2 and c = 5

So,

$x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(3)(5)}}{2(3)}\\\\x=0.333,4.667$

Hence, this is the required solution.
