The second from last cuz S.A. Only have one way to it
Answer:
a) 8-bit representation = 11111010
b) 8-bit representation = 00011001
c) 8-bit representation = 11111000
Step-by-step explanation:
a. 1010
4-bit 2's complement binary representation
decimal value = -6
Since the number is negative pad with 1 to the left of MSB
8-bit representation = 11111010
b. 011001
6-bit 2's complement binary representation
decimal value = 25
Since the number is positive pad with 0 to the left of MSB
8-bit representation = 00011001
c. 1111111000
10-bit 2's complement binary representation
decimal = -8
Since the number is negative discard left most two bits
8-bit representation = 11111000

Answer:
Hey it’s 283
Step-by-step explanation:
Answer:
16. Angle C is approximately 13.0 degrees.
17. The length of segment BC is approximately 45.0.
18. Angle B is approximately 26.0 degrees.
15. The length of segment DF "e" is approximately 12.9.
Step-by-step explanation:
<h3>16</h3>
By the law of sine, the sine of interior angles of a triangle are proportional to the length of the side opposite to that angle.
For triangle ABC:
- ,
- The opposite side of angle A ,
- The angle C is to be found, and
- The length of the side opposite to angle C .
.
.
.
Note that the inverse sine function here is also known as arcsin.
<h3>17</h3>
By the law of cosine,
,
where
- , , and are the lengths of sides of triangle ABC, and
- is the cosine of angle C.
For triangle ABC:
- ,
- ,
- The length of (segment BC) is to be found, and
- The cosine of angle A is .
Therefore, replace C in the equation with A, and the law of cosine will become:
.
.

For triangle ABC:
- ,
- ,
- , and
- Angle B is to be found.
Start by finding the cosine of angle B. Apply the law of cosine.

For triangle DEF:
- The length of segment DF is to be found,
- The length of segment EF is 9,
- The sine of angle E is , and
- The sine of angle D is .
Apply the law of sine:
