The ratio of the perimeters of two similar triangles is 4:3. What are the areas of these triangles if the sum of their areas is 130 cm^2?

Answers

Answer:

the areas of these triangles are 83.2cm² and 46.8cm²

Step-by-step explanation:

1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:

4²:3²

16:9

2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:

130(16/16+9)

130(0.64)

=83.2cm²

3. The area of the smaller triangle is:

130(9/16+9)

130(0.36)

46.8cm²

Answers

Answer:

y=1/3x+3

Step-by-step explanation:

We can write this in a y=mx+b format.

b is the y-intercept and m is the slope.

The y-intercept is where x=0, or where the line intersects the y-axis. We can see that there is a point on the y-axis: (0,3). Therefore, the y-intercept, or b, is 3.

So far, we have y=mx+3.

Now we can find the slope with rise over run. (rise being the change in y and the run being the change in x.)

From one point to the other, it goes up 1 (the rise) and over 3 (the run).

m=rise/run=1/3.

y=1/3x+3.

Hope this helped.

Solve for x in the picture please.

Answers

Answer:

X=20

Step-by-step explanation:

The 3 angles all add up to 180º because they are a straight line.

3x + 80 + 2x = 180

5x + 80 = 180

5x + (80-80) = 180-80

5x = 100

5x/5 = 100/5

X=20

Hope this helps!

Answer
Straight line = 180
So
3x+80+2x=180
5x +80 =180
5x=180-80
5x=100
x=100/5
x=20

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The given function is

Answers

Answer:

R = 29

S = 61

T = 116

Step-by-step explanation:

The angle opposite to it is 29 so therefore it is 29 degrees as well.

There is a 29 degree angle and a 90 degree angle which is 119, and since the total degrees in a triangle is 180, 180 - 119 = 61.

There is a 64 degree angle which means that there is a 64 degree angle on the other side of those lines.

Since the total degrees of those crossing lines are 360,

64 + 64 = 128.

360 - 128 = 232

232/2 since 232 is the two remaining angles togther, 116.
