O is the centre of the circle and ABC and EDC are tangents to the circle. Find the size of angle BCD. You must give reasons in y
Simora [160]

Answer:

mBCD = 28°

Step-by-step explanation:

The angle mBFD inscribes the arc mBD, so we have that:

mBFD = mBD/2

76 = mBD/2

mBD = 152°

The angle mBOD is a central angle related to the arc mBD, so we have that:

mBOD = mBD = 152°

In the quadrilateral BODC, the sum of internal angles needs to be equal to 360° (property of all convex quadrilaterals). The angles mCBO and mCDO are right angles, because EDC and ABC are tangents to the circle.

So, we have that:

mBOD + mCDO + mBCD + mCBO = 360

152 + 90 + mBCD + 90 = 360

mBCD = 360 - 90 - 90 - 152

mBCD = 28°

A tourist views a deer from a height of 45 feet. The horizontal distance between the tourist and the deer is 130 feet. At what a
jeka94

Answer:

19°

Step-by-step explanation:

You can form a right triangle using the given information. The height would be the opposite side of the triangle and the  the distance between the tourist and the deer would be the adjacent side. To find the angle we can use the tangent

Tan x = opposite side / adjacent side

Tan x = 45/130

x = Tan^-1 (45/130)

x = 19°
