This is cross multiplication.
513.74 times x =513.74x
16.26 times 100=1626
Now there is 1626=513.74x
Do 1626 divided by 513.74 which is 3.16502511
-7 and -.9 are two possible addends
Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
<em>(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5</em>
<em>This would get of / 5 so you don't need to divide by 5</em>
362 + x = 460
Subtract 362 from each side
x = 98
The value of csc theta from the given diagram is 15/12
<h3>Application of SOH CAH TOA</h3>
The given triangle is right angle triangle. According to trigonometry identity
csc theta = 1/sintheta
Given
- Opposite = 12
- Hypotenuse = r
sin theta = 12/r
Determine the value of r
r² = 9² + 12²
r² = 81 + 144
r² = 225
r = 15
sin theta = 12/15
Determine the value of csc theta
csc theta = 15/12
Hence the value of csc theta from the given diagram is 15/12
