The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
Answer: 800
Divide 3200 by 4 to get 800.
Answer:
As all even square numbers are divisible by 4, the even numbers of the form 4n + 2 are not square numbers. As all odd square numbers are of the form 4n + 1, the odd numbers of the form 4n + 3 are not square numbers.
Answer:
the firstn one
Step-by-step explanation:
check the picture below.
as you see in the picture, all 4 angles add up to 180°, and since we know that KM is an angle bisector to ∡NKL, then that simply means ∡NKM = ∡LKM.
