Answer:

55°, 40° and 85°

Step-by-step explanation:

For a given triangle, the sum of its interior angles is equal to 180°.

Here, the interior angles are 2x + 15, x+ 20 and 3x +25.

∴ 2x+15+x+20+3x+25=180\\6x+60=180\\6x=180-60\\6x=120\\x=20

Now, plug in 20 for x and evaluate each angle.

So, 2x+15= 2(20)+15=55°

x+20=20+20=40°

3x+25=3(20)+25=60+25=85°

Therefore, the measures of the angles of the triangles are 55°, 40° and 85°.

The heights of women aged 20 to 29 follow approximately the N(64, 2.72) distribution. Men the same age have heights distributed
Softa [21]
The z-score for men at 64 inches is:
z=\frac{64-69.3}{2.84}=-1.866
Using a standard normal distribution table, we can see that the cumulative probability for a z-score of -1.866 is 0.031.
The answer is 3.1%.

What is the answer ?
nekit [7.7K]
That "3" is a measure of units halfway across the square. So, the total distance across the square is 6.
Since this is a square, and since, with squares, all sides are equal, the width of the square would also be 6.
To find the area, simply multiply the base by the height.
6*6=36

So, the answer is 36 square units.
