Answer:
Step-by-step explanation:
Given:
We need to find the m ∠ DEF.
Solution:
Now we can say that;
By inscribed angle theorem;
"The measure of the angle is twice the measure on the arc subtended by it."
so we get;
Applying distributive property we get;
Combining the like terms we get;
Dividing both side by 7 we get;
Hence
The triangle with side lengths 4,11,15 does not even exist.
According to the Triangle Inequality Theorem, in order for the triangle to even exist, the sum of the two shorter lengths must be strictly greater than the length of the third side.
4 + 11 = 15.
15 is not greater than 15.
Answer:
y=3
Step-by-step explanation:
10y-50=-20
first add 50 to both side
10y=30
then divide 10 in the both side
y=30/10
so the answer is y=3
Answer:
100 yards of fabric
Step-by-step explanation:
12 divided by 3 = 4 yards of fabric per costume
4 x 25 = 100 yards of fabric
Answer:
Step-by-step explanation:
You can do this in a conventional mathematics way by showing each digit as an increasing power of 8, starting with zero
E.g 325 octal
(3 * 8 2 ) + (2 * 8 1 ) + (5 * 8 0 ) = (3 * 64) + (2 * 8) + (5 * 1)
i.e 192 + 16 + 5 = 197 decimal
Note: any number raise to power of 0 in indices is equal to 1
