Answer:
109.5; B
Step-by-step explanation:
From your identity,
CosA = adjacent/ hypothenus
A represent an arbitrary angle between the sides in question.
In the question above, A=64
Hypothenus is the longest side and adjacent is the side just below the angle .
In the above case,
Hypothenus= X
adjacent =48
This means;
Cos64 = 48 /X
X = 48 / cos64; [ from cross multiplication and diving through by cos64]
X = 48 /0.4383 [ cos64 in radian = 0.4383]
= 109.51
= 109.5 to the nearest tenth.
Note( do your calculation of angle in radian or else, you won't get the answer)
9514 1404 393
Answer:
- no parts have the same color (0)
- yellow, blue, red
- percentages can be written in several forms: fraction, decimal, for example. The sectors can also be identified by their angle measures.
- see attached
Step-by-step explanation:
1. The seven different sectors have seven different colors. No parts have the same color.
2. The attached table lists the sectors in decreasing order of size. The largest three are yellow, blue, red.
3. Percentages can be written a number of ways. They can be written as decimal numbers, or as fractions. In a pie chart, the sectors can also be given an angle measure.
4. Fraction equivalents of the percentages are shown in the attached.
5. Reduce fraction equivalents of the percentages are shown in the attached.
Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.
