The total degrees in a triangle is 180. if you add the angles up, it should equal. if we say that the angle of the third angle is y, our equation looks like this
y+x+86=180
if we solve for y, we get
y=180-86-x, which you can solve for for your answer
He went around 24 times and 4 times is a mile so 24/4 will tell us how many miles he biked. He biked 6 miles in thirty minutes. The formula distance = rate(time) will tell you how fast he is going.
6 = r(1/2) divide each side by 1/2 (The time has to be in hours)
12 = r
So he was going 12 miles an hour.
Answer:
the common difference is 10
Step-by-step explanation:
Part (a):
The sum of the interior angles of a triangle is 180°.
The given measurements are:
20°, 60° and 100°
Sum of the given measurements = 20 + 60 + 100 = 180°
Therefore, these measurements can form a triangle
Part (b):
The sum of the interior angles of a triangle is 180°.
The given measurements are:
85° , 89° and 6°
Sum of given measurements = 85 + 89 + 6 = 180°
Therefore, these measurements can form a triangle
Hope this helps :)
