Remember
so
notice that 200=2*2*2*5*5, so x cannot be a whole number
take the log base 10 of both sides
divide both sides by
if we used
instead of
we would get
because
Drawing a diagram to represent the information you've given, the only angle we are missing is B. We can find that by subtracting the two we're given from 180:
180 - 90 - 48.8 = 41.2
<em>m</em>∠<em>B</em> = 41.2°.
We can use the angles and the one side we're given to find the remaining sides. Since we do not know the length of the hypotenuse, AB, we cannot use sine or cosine. We must use tangent (the ratio for tangent is opposite/adjacent):
Multiply both sides by 1.6:
This is the length of side AC, which is opposite to angle B.
To find the length of AB we can use the Pythagorean Theorem:
The length of side AC, the hypotenuse, is 4 inches.
Answer: the last one I think
no sure sorry
Step-by-step explanation:
Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
x=34
