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
Answer:
The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9. .
Step-by-step explanation:
From the general properties or laws of logarithm, we have the
where both log are now express in the natural logarithm base.
i.e
hence we can express our .
the value of ln7 is 1.9459 and ln4 is 1.3863
Hence .
180=(12x+8)+(8x+12)
180=20+20x
-20. -20
160=20x
20. 20
X=8
B)8
3 1/7 Because there are three multiples of 7 and 1 remainder.
