Answer:
Step-by-step explanation:
In all 30-60-90 triangles, the side lengths are in the ratio , where is the side opposite to the 30 degree angle and is the hypotenuse of the triangle. Since the side opposite to the 30 degree angle is marked as 3, the value of must be .
Alternatively, we can use basic trig. for a right triangle to solve. In any right triangle, the tangent of an angle is equal to its opposite side divided by its adjacent side. Thus, we have:
Answer: a) x= 68, b) 108°, c) 72°, d) 255°.
Step-by-step explanation:
Since we have given that
The interior angles of hexagon:
(2x+17), (3x - 25), (2x+49), (x+40), (4x-17) and (3x - 4).
So, it becomes :
ii. Find the smallest interior angle of the quadrilateral.
iii. Find the largest exterior angle of the quadrilateral.
iv. Find the largest interior angle of the quadrilateral.
Hence, a) x= 68, b) 108°, c) 72°, d) 255°.
The relationship is negative 4
