Answer: how do we have the same question need the answer too
Step-by-step explanation:
The length of the 2D cross-section = 22cm
Breadth of 2D cross-section = 12cm
Since it's inside a rectangular prism, it's area will be given by the formula of area of a rectangle.
→ Area of 2D cross-section = 22×12 = 264 cm²
Answer:
the coordinates of point A are (1, 4)
the coordinates of point B are (-3, 1)
the shape is a trapezoid
Step-by-step explanation:
Since we have 90° angle that means that side opposite of it is hypotenuse, so it goes:
a=10cm b=6 c=?
The inside angle where that is not labelled you can find as angles on a straight line = 180°. From this you can find that the angle is 180-40=140°. This shape is a pentagon so the sum of the interior angles is 180(5-2)=540°. So this means 68+124+76+140+x=540. Rearrange for x to get x=132°.
