Please help!!!! :) !!!!!!!!

Mathematics
1 answer:
Musya8 [376]3 years ago
6 0

Answer:

x = 3

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are equal, thus

x - y = x + 2 ( subtract x from both sides )

- y = 2 ( multiply both sides by - 1 )

y = - 2

and

4x + 2y = 2x - y

substitute y = - 2

4x - 4 = 2x + 2 ( subtract 2x from both sides )

2x - 4 = 2 ( add 4 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Help me. I don't get it :(

10) because of the alternative exterior angle theorem angle 2 is the same as angle 8 and because of the vertical angles congruence theorem angles 2 and 4 are also the same so if angle 2 is the same as both 4 and 8,
then x=5 because 4x+57 =77
subtract 57 from both sides and 4x=20
divide both sides by 4 and x equals 5

Given: △RST ~ △VWX
tatiyna

Answer:

Given

Step-by-step explanation:

Given that: △RST ~ △VWX, TU is the altitude of △RST, and XY is the altitude of △VWX.

Comparing △RST and △VWX;

TU ~ XY (given altitudes of the triangles)

<TUS = <XYW (all right angles are congruent)

<UTS ≅ <YXW (angle property of similar triangles)

Thus;

ΔTUS ≅ ΔXYW (congruent property of similar triangles)

<UTS + <TUS + < UST = <YXW + <XTW + <XWY = 180^{0} (sum of angles in a triangle)

Therefore by Angle-Angle-Side (AAS), △RST ~ △VWX

So that:

\frac{TU}{XY} = \frac{US}{YW} (corresponding side length proportion)

Please help meeee I don't know this
Vanyuwa [196]

Answer:

\boxed {m = -\frac{5}{7}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First Point: (x_{1} , y_{1})

Second Point: (x_{2}, y_{2})

-Substitute both points:

First Point: (5, 11)

Second Point: (19, -1)

m = \frac{-1 - 11}{19 - 5}

-Solve for the slope:

m = \frac{-1 - 11}{19 - 5}

m = \frac{-10}{14}

\boxed {m = -\frac{5}{7}}

Therefore, the slope is -\frac{5}{7}

Solve by taking the square root of both sides 3(x-1)^2-162=0
Natali5045456 [20]
We know that: <span>3(x-1)^2-162=0
or (x-1)</span>²= 162:3
and (x-1)²= 54
we <span>take the square root of both sides 
* x-1=</span>√54= 3√6 or x=1+3√6
* x-1= -<span>√54= -3√6 or x=1-3√6
This equation has 2 solutions</span>

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second wi
Alenkasestr [34]

195 students voted for eagle in the election

What is ratio?

Ratio means expressing the a figure as a fraction of total figure, in the case of falcon, the number of students that voted for falcon is seen as 5 whereas the total number of students that voted is 8 whereas for eagle, the total number of students that voted for eagle is 1 compared to 3 which represents the total number of votes cast.

In a bid to determine the number of students that voted eagle in the election, we would simply multiply total votes of 536 by 1/3

votes for eagle=1/3*586

votes for eagle=195 votes

We have rounded to the nearest whole number since number of votes cannot be fractional
