Answer:

35º

Step-by-step explanation:

It says that the total degree of WXZ is 105º. If m∠2 is two times m∠1, that means that there are three total parts. You divide 105º by 3 and you get 35º. Therefore your answer is 35º

Answer:

m∠1 = 35°

Step-by-step explanation:

For simplicity, let the measure of angle 1 be represented by α. Then the measure of angle 2 is 2 times that, or 2α. Those two angles together total the measure of angle WXZ, which is 105°.

α +2α = 105°

3α = 105° . . . . . . . . . . collect terms

α = 105°/3 = 35° . . . . divide by the coefficient of α

The measure of angle 1 is 35°.

_____

The measure of angle 2 is 70°.

Triangle RSU is an equilateral triangle. RT bisects US. Find x and y. (y+12)°

Nat2105 [25]

Answer:

x= 4

y = 6

Step-by-step explanation:

Given:

RSU is equilateral triangle

RT bisects US

To Find:

x and y

Solution:

Step 1: Finding the value of x

In an equilateral triangle,

All the sides are equal

Since RT bisects US

US = 3x+3x

Also RU = 4x+8

Then ,

we know that

RU = US

$4x+8 = 3x+3x$

$4x+8 = 6x$

$4x+ 8 -6x = 0$

$-2x+8 = 0$

$-2x = -8$

$x = \frac{-8}{-2}$

$x = 4$

Step 2: Finding the value of y

In an equilateral triangle,

All the angles are equal to 60 degrees

Then $\angle URS = 30^{\circ}$

But RT bisects US

Then

$\angle URS = \angle URT +\angle TRS = 60^{\circ}$

where

$\angle URT and \angle RTS$ are equal

So

$\angle RTS = 30^{\circ}$

In the figure

$30^{\circ} = 5y^{\circ}$

$y^{\circ}= \frac{30^{\circ}}{5}$

$y^{\circ} = 6$

Which expressions are equivalent?

trapecia [35]

Only 3(a−b) and 3a−3b are equivalent

Further explanation:

We have to evaluate each expression to evaluate if the expressions are equivalent or not.

So,

<u>For 3(a−b)</u>

$3(a-b)\\Distributing\ 3\ in\ bracket\\3.a-3.b\\=3a-3b$

As we can see that 3(a-b) results in 3a-3b so these are equivalent

<u>For 2a(2+b)</u>

$2a(2+b)\\Distributing\ 2a\\2a.2+2a.b\\=4a+2ab$

As we can see that 2a(2+b) doesn't result in 4ab so these are not equivalent

Hence,

Only 3(a−b) and 3a−3b are equivalent

X^2-x+12 solve using the quadratic formula

devlian [24]

The quadratic formula is $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$ .

From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:

$x=\frac{-(-1(-1)\pm\sqrt{(-1)^2-4(1)(12)} }{2(1)}$

Because there is a square root of a negative number, there is no solution.
