I got 180 because (although the picture is smaller and digital meaning I may be off) angle AOD = 85 degrees while angle BOC = 95. 95 + 85 = 180.

The triangle formed by radii to the ends of a chord of a circle is an isosceles triangle. That means the central angle will be 180° less twice the base angle shown.
.. ∠AOB = 180° -2*35° = 110°
.. ∠COD = 180° -2*55° = 70°

Then the desired sum is
.. ∠AOD +∠BOC = 360° -110° -70° = 180° . . . . . . corresponds to selection A

Leokris [45]

The geometry was developed by a Greek mathematician called Euclid and developed to meet some practical need in surveying, construction, astronomy, and various crafts.

In this question,

Early geometry was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts.

It was developed by a Greek mathematician called Euclid. This branch of geometry deals with terms like points, lines, surfaces, dimensions of the solids, etc.,

In several ancient cultures there developed a form of geometry suited to the relationships between lengths, areas, and volumes of physical objects. This geometry was codified in Euclid's Elements about 300 bce on the basis of 10 axioms, or postulates, from which several hundred theorems were proved by deductive logic.

Hence we can conclude that the geometry was developed by a Greek mathematician called Euclid and developed to meet some practical need in surveying, construction, astronomy, and various crafts.

Oksanka [162]

Answer:

3) y = 50 * 2¹²ˣ

2) y = 80 * 2⁸ˣ

Step-by-step explanation:

1 day = 24 hours

Number of 2-hour periods in 1 day = 24 ÷ 2 = 12

Number of 3-hour periods in 1 day = 24 ÷ 3 = 8

Colby's experiment:

y = 50 * 2¹²ˣ

Jaquan's experiment:

y = 80 * 2⁸ˣ

What are the coordinates of the midpoint of the line segment with endpoints B(9, −8) and C(2, −5) ? PLEASE ANSWER TODAYYYY
Oduvanchick [21]
The answer is (5.5,-6.5) because you find the midpoint for the x-axis which is 9+2 then divide by 2 then do the same for the y-axis and place them together.
