Answer:
Pythagorean Theorum is defined in Mathematics by a^2 + b^2 = c^2.
One leg (a) is 5. The other leg (b) is 13.
Let's use Pythagorean Theorum.
5^2 + 13^2 = c^2
5 • 5 = 25
13 • 13 = 169
25 + 169 = 194.

Answer:
a) 137.9°
b) 12.2° (please refer to explanation because I didn't know what to round to)
Step-by-step explanation:
1a) A supplementary angle will equal 180°, so you must subtract 42.1 from 180
180-42.1 = 137.9
1b) A complementary angle will equal 90°, so you need to use the expression given and add an x for the other part of 90°
8x-20+x = 90
9x-20=90
9x=110
x=12.2
Answer:
30.25pi in terms of pi
94.985 In terms of 3.14
Step-by-step explanation:
Okay since the circumference is 11pi we know d = 11.
Meaning r = 5.5
We can solve this in terms of pi or 3.14, for this I will use both.
The formula for an area of a circle is pi*r^2
So,
5.5 * 5.5 = 30.25.
In terms of pi, the answer would be 30.25pi
In terms of 3.14 the answer would be 94.985
