I really dont understand this question, help? i dont need steps or anything
Agata [3.3K]

Answer:

Step-by-step explanation:

135 degrees is an exterior angle. meaning the interior angle is 45. meaning x is 45 because of the isosceles triangle theorem that states if two sides are equal on a triangle then their angles opposite those are congruent. a triangle measures up to 180 in general. so 45 plus 45 is 90. 180 minus 90 is 90. so angle x is 45 and angle y is 90

Is this multiplication? Can you also help me with the answer!?
vredina [299]

Answer:

84,375 m^2

Step-by-step explanation:

We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).

Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.

Area of a square is length times width.

Total area = 4\times(\frac{1}{2}\times 225 \times 75)+225\times225 = 84375 m^2
