Answer:
64 degree
Step-by-step explanation:
The tangent is perpendicular to the normal. In case of circle the normal is the radius which passes from the center of the circle.
Here Angle BAC = 90 degree (as the angle between the tangent and normal)
Angle BAC = 26 degree,
The sum of all the angles in a triangle is 180 degree,
So,
angle BAC + angle ABC + angle ACB = 180 degree
26 degree + angle ABC + 90 degree = 180 degree
angle ABC = 64 degree
3/4+2/5 is 1 and 3/20 because first, you have to find the common denominator, which is 29. Next you have to multiply the numerator by the number that you multiplied the denominator by. You will then get 15/20+8/20. Next you add 15+8, which is 23. Then you get 23/30, which you then simplify to 1 and 3/20.
Answer:
Step-by-step explanation:
The ratio everything is 1:2. DE joins two midpoints. There are many properties involved in saying that. The most important for this question is that DE = 1/2 BC
That means that the sides in the small upper triangle (ADE) are 1/2 the size of the sides in the larger triangle.
So if DE = 8 then BC must be twice as big or BC = 16
