Multiply the diagonals together and then divide by two
4 x 6 / 2
so the answer would be 12yd
The surface area of the square prism is 115 square inches
<h3>surface area of a pyramid</h3>
The surface area of a pyramid is equivalent to the sum of the faces of the pyramid
For the given square pyramid;
TSA = (5*5) + 4(1/2 * 9 * 5)
Simplify to have;
Surface area =25 + 4(45/2)
Surface area = 25 + 180/2
Surface area = 25. + 90
Surface area = 115 square inches
Hence the surface area of the square prism is 115 square inches

Answer: Honey you have to do that no one on here can plus just a tip
(use a ruler it makes it easy)
m∠a = 56°, m∠b = 34°, m∠c = 56°
Solution:
<em>Sum of the adjacent angles in a straight line is 180°.</em>
⇒ m∠a + 124° = 180°
⇒ m∠a = 180° – 124°
⇒ m∠a = 56°
∠a and ∠c are vertically opposite angles.
Vertical angle theorem:
<em>If two lines are intersecting, then the vertically opposite angles are congruent.</em>
⇒ ∠a ≅ ∠c
⇒ m∠a = m∠c
⇒ m∠c = 56°
<em>Sum of the adjacent angles in a straight line is 180°.</em>
m∠b + 90° + m∠c = 180°
m∠b + 90° + 56° = 180°
m∠b + 146° = 180°
m∠b = 180° – 146°
m∠b = 34°
Hence m∠a = 56°, m∠b = 34°, m∠c = 56°.
