We know that
<span>the rotation of a solid does not modify the values of the internal angles of the solid
</span>therefore
interior angle after 90° rotation=interior angle before 90° rotation
interior angle after 90° rotation=108°
the answer is the option D 108 °
Answer: a). 136 degree. b). A kite
Explanation:
360 = POR + OPT + ORT + 44
OPT = ORT = 90 (line TP and TR tangent to the circle)
360 = POR + 90 + 90 + 44
POR = 360 - 224
POR = 136
B). OPTR is a kite because OP = OR and TP = TR
Definition of a kite:
A quadrilateral whose 4 sides can be grouped into two pairs of equal sides that are adjacent to each other.
Answer:
357.5ft^3
Step-by-step explanation:
solve for bottom reticular prism
8 * 10 * 4
320ft^3
solve for top triangular prism
((3*5)/2)*5
37.5ft^3
add top and bottom
320+37.5
357.5ft^3
Answer:
Step-by-step explanation:
Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:
17x+3 = 57
because they are corresponding sides of both triangles. To further solve the equation:
17x = 54 --> x = 54/17 --> <u>3 3/17</u>
Same thing for Y. lines PX and FD are congruent, so, you can say:
4y-3 = 54
4y=57
<u>y= 14.25</u>
