Actually Welcome to the Concept of the Quadrilaterals.
Basically we know that, the sum of opposite angles of a quadrilateral inscribed in a circle is always 180°.
so applying this law here, we get as,
2X + (3X-10) = 180°
=> 5X - 10° = 180°
=> 5X = 190°
=> X = 190°/5
=> X = 38°
thus the angle X= 38°.
This is the answer. Let me know if i'm correct.
Answer:
2 meters
Step-by-step explanation:
The formula for finding the volume of a triangular prism is:
V = 1/2ba * h where b = base length, a = height of base and h = height of prism. In this case, we're solving for a. We know that V = 4.5, b = 1.5 and h = 3 so:
4.5 = 1/2 * 1.5 * a * 3
4.5 = 2.25a
a = 2 meters
First option
49+59+72=180
and a triangle needs 180 degrees total
