Answer:
72 cm
Step-by-step explanation:
You can solve this problem using the properties of the 45-45-90 right triangle. Assuming the 12 cm is a diagonal of the square, each side of the square can be modeled as x, and the diagonal will be x
.
This means 
, so 
.
Next, to find the area of the square you take the square of any of its sides. Since x is the length of one side, and , you can square 
to get the area. This is equal to 
or 72 cm.
The statement that is true about mass are:
- One kilogram is 1,000 times greater than one gram.
- Kilograms are greater than grams
<h3>What is mass?</h3>
The mass is the physical measuring quantity that measures the weight or body inertia of a substance.
It also pinpoints the strength of an object's gravitational abstraction to other bodies.
The unit of mass can be expressed in;
A kilogram usually contains 1000 grams. Thus, we can conclude that:
- One kilogram is 1,000 times greater than one gram.
- Kilograms are greater than grams.

Answer:
67 degrees
Step-by-step explanation:
If angle a is 113 degrees, angle d will be 113 degrees subtracted from 180 degrees. Because angles in a straight line adds up to 180 degrees.
Answer:
256/3 = 85 1/3 square inches
Step-by-step explanation:
The dimensions of the first inscribed triangle are 1/2 those of the original, so its area is (1/2)² = 1/4 of the original. The area of the original is ...
A = (1/2)bh = (1/2)(16/√2)(16/√2) = 64 . . . . square inches
The sum of an infinite series with first term 64 and common ratio 1/4 is ...
S = a1/(1 -r) . . . . . . for first term a1 and common ratio r
= 64/(1 -1/4) = 64(4/3) = 256/3 . . . . square inches
The sum of the areas of the triangles is 256/3 = 85 1/3 square inches.
