2. One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the measures of the first two angles. Find the measure of each angle. [Hint: the sum of the three angles in a triangle equals 180°.] PLEASE SHOW YOUR WORK I WILL MAKE BRAINLIST PLEASE!!!!!!!

Answer:

first angle = 25 degrees

Second angle = 35 degrees

Third side = 120/degrees

Step-by-step explanation:

Let the size of the second angle be x degrees.

One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.

The measure of the third angle is   twice the sum of the measures of the first two angles. This means that   The third angle = 2( first angle + second angle). So the size of each angle is  

First angle (x + 10) degrees  

Second angle = x degrees

Third angle = 2(x + 10 + x) =  (4x + 20) degrees

Sum of angles in a triangle = 180  degrees. Therefore,  x + 10 + x + 4x + 20 = 180 degrees  6x + 30 = 180

6x = 180 - 30 = 150

x = 150/6 = 25 degrees

First angle = x + 10 = 25 +10 = 35

Third angle = 4x + 20 = 4 × 25 + 20

= 100+ 20 = 120 degrees

Hope this helps

Answer:25(1st angle),35(2nd angle),120(3rd angle)

Step-by-step explanation: (/ stands for divide)

180/6=30 (sum of angles/total units=value of one unit, third angle is 4 units as it is twice the sum of first two angles)

30x4=120 (value of unitxnumber of units of 3rd angle=3rd angle)

30x2=60 (value of unitxfirst angle+second angle total units=value of 1st angle+2nd angle)

(60-10)/2=25(1st angle)

25+10=35(2nd angle)

CHECK: 35+25+120=180

hope you get it :)

How could you apply a Property of Equality to this equation to solve for x?

X + 2 = 4

I need a quick equation in y=mx+b form that shows their total miles hiked after x number of weeks.

Help? Writing equations in slope-intercept.
Which of the following is the CORRECT slope-intercept form of the equation -4x + 2y = 14?
There is only one choice.

y = 2x + 7
y = 4x + 14
y = -2x + 7
y = -4x + 14

Tony writes an equation to represent the distance he walks in meters, d, in relation to the number of minutes he walks, m.

d = 108m

Mark has created a table to record the number of minutes it took him to walk different distances in meters.

Time
(minutes)
Distance
(meters)
10
1,100
20
2,200
40
4,400
Assuming that Tony and Mark both walk at a constant rate, the unit rate for Tony is
meters per minute and the unit rate for Mark is
meters per minute.

On a graph, the line representing Tony’s distance covered with respect to time would be
Mark’s line. So, Tony’s walking speed is
Mark’s.
