Since M is the mid point of the triangle, the distance of M from A,B and C is equal which means AM = BM = CM.

Therefore, MAB = MBA. In triangle MAB, MAB=45 degrees.

sum of angles in a triangle = 180 deg. So, sum of angles MAB and MBA = 180 - BMA = 180 -45 = 135.

Since both MAB and MBA are equal , MAB = 135/2 = 67.5

In triangle AMC, MAC = MCA . Therefore MAC = 30/2 = 15 deg.

Therefore total BAC = MAC + MAB =82.5 deg.

Therefore, MAB = MBA. In triangle MAB, MAB=45 degrees.

sum of angles in a triangle = 180 deg. So, sum of angles MAB and MBA = 180 - BMA = 180 -45 = 135.

Since both MAB and MBA are equal , MAB = 135/2 = 67.5

In triangle AMC, MAC = MCA . Therefore MAC = 30/2 = 15 deg.

Therefore total BAC = MAC + MAB =82.5 deg.

Lots and lots and lots. When you think the angle is nearly 180 degrees or a straight line, it must have lots and lots of sides.

The total of the interior angles of a polygon is given by (n-2)180, so the angle of each interior angle of a regular polygon is given by ((n-2)180)/n.

Now we set this to be equal to 176 and solve for n.

(n-2)180 = 176

-----------

n

Multiplying both sides by n, we get (n-2) 180 = 176n

Expanding the left side of the equation, 180n - 360 = 176n

Subtracting 176n from both sides and adding 360 to both sides, we get

180n - 176n = 360

4n = 360

Dividing both sides by 4, n = 90

Thus, you need a regular polygon of 90 sides to get an internal angle of 176 degrees.

Hopefully you don't have to construct it.

a^2 + b^2 = c^2

a squared + b squared = c squared, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides in a right-angled triangle.

It should be 1:4. Reasons

A quarter equals to 25 pennies and a 100 pennies are equal to 1 dollar. So having these sorted out means 1:4
