From the description given for the triangle above, I think the type of triangle that is represented would be a right triangle. This type of triangle contains a right angle and two acute angles. In order to say or prove that it is a right triangle, it should be able to satisfy the Pythagorean Theorem which relates the sides of the triangle. It is expressed as follows:
c^2 = a^2 + b^2
where c is the hypotenuse or the longest side and a, b are the two shorter sides.
To prove that the triangle is indeed a right triangle, we use the equation above.
c^2 = a^2 + b^2
c^2 = 20^2 = 10^2 + (10sqrt(3))^2
400 = 100 + (100(3))
400 = 400

∠ Given are (x + 18)° , x° , 4x° and one Angle is 90° as per diagram
Let ,
1st∠ = (x + 18)°
2nd∠ = x°
3rd∠ = 4x°
so ,

substituting x = 12 at the place of x .
= x° + 18°
= 12° + 18 °
1st∠ = 30°
__________________________________
= x°
2nd∠ = 12°
__________________________________
= 4x°
= 4(12)°
3rd∠ = 48°

Answer:</h3>
67 miles
<h3>
Step-by-step explanation:</h3>
On Monday, Jullo ran <u>39 miles.</u>
On Tuesday, he ran <u>24 miles.</u>
On Wednesday, he ran <u>4 miles.</u>
<u>Finding the total miles:</u>
Total miles ran on Monday, Tuesday, and Wednesday = 39 + 24 + 4
= 67 miles
Hm. good question! multiply 5x2 i believe, which should be 10. Hope I helped!
Biased estimators are Sample median & sample standard deviation
Unbiased are sample mean sample variance and sample proportion
Neither choice include population mean, standard deviation proportion and variance
