Two triangles ∆DEF
and ∆<span>MNO are equivalent to each other, then their
corresponding angles and sides are also equal to each other. Therefore option C
is correct, which is angle EDF is equal to angle NMO. It is also mentioned in
the attached diagram. </span>
Answer:
a) 29% b) 22%
Step-by-step explanation:
The quantities must be expressed in the <u>same units</u>.
a) compare 35 minutes to 2 hours. 2 hours is 2 x 60 = 120 minutes.
35/120 = .291667 = 29%
b) compare 650 grams to 3 kilograms. 3 kg = 3 x 1000 = 3000 g.
650/3000 = .21667 = 22%
Answer: .33 repeating
Step-by-step explanation:
Properties of a rhombus:
1. the all sides are equal
2. opposite angles are equal
3. consecutive angles are supplementary
4. The diagonals bisect the angles.
5. The diagonals are perpendicular bisectors of each other.
==================================================
∵ abcd is <span>a rhombus:
</span>
<span>∴ ∠ abc = 2 ∠ebc = 2 * 36° = 72° ⇒⇒⇒ property number (4)
</span>
<span>∴ ∠ dab = 180 - ∠abc = 180° - 72° = 108° </span><span>⇒⇒⇒ property number (3)
</span>
∴ ∠ dae = 108°/2 = 54° <span>⇒⇒⇒ property number (4)

The surface area of square pyramid is 64 ft²
What is square pyramid?
In terms of geometry, a square pyramid is a pyramid with a square base and four lateral faces. A pyramid is a type of polyhedron with three or more triangular faces that meet above its base (the apex). A square pyramid is a pentahedron, a three-dimensional shape with a total of five faces. The Great Pyramid of Giza is a well-known example of a real-life pyramid. When we learn about pyramids, we must also learn other concepts that are related to them, such as the volume and area of the pyramid. In this article, we will learn what a square pyramid is, its types, characteristics, surface area formulas, and volume formulas with numerous examples and solutions.
For a square pyramid, the surface area is given by the following equation:
SA = a^2 + 4(a)(h)
where a is the side length of the base and h is the slant height.
In this case, a = 4 and h = 3. Therefore,
SA = 4^2 + 4(4)(3)
SA = 16 + 48
SA = 64 ft^2
