<u>Answer</u>
A) 40°
<u>Explanation</u>
Assuming that the angles are measured from the center, we can use the properties of a circle to find <CAE.
Angles subtended by at the center by the same arc double the angle at the circumference.

Answer:
x = 6.6
Step-by-step explanation:
Data obtained from the question include the following:
Angle X = 15°
Angle Y° = 23°
Side y = 10
Side x =..?
The value of side x can be obtained by using the sine rule as shown below:
x/Sine X = y/Sine Y
x/Sine 15 = 10/Sine 23
Cross multiply
x × Sine 23 = 10 × Sine 15
Divide both side by Sine 23
x = (10 × Sine 15) / Sine 23
x = 6.6
Therefore, the value of x is 6.6.
Answer:
x = 2
Step-by-step explanation:
x + 5 = 2x + 3 ( subtract x from both sides )
5 = x + 3 ( subtract 3 from both sides )
2 = x
Answer: x < 6
<u>Step-by-step explanation:</u>
5x - 9 < 21
