14
subtract 9 from 23. you get 14, 14-23=-9
Given:
m∠APB = 74°
To find:
The measure of ACB
Solution:
The measure of the central angle is congruent to the measure of the intercepted arc.
⇒ m(ar AB) = m∠APB
⇒ m(ar AB) = 74°
The complete angle of the circle is 360°.
⇒ m(ar ACB) + m(ar AB) = 360°
⇒ m(ar ACB) + 74° = 360°
Subtract 74° from both sides.
⇒ m(ar ACB) = 286°
The measure of arc ACB is 286°.
Answer:
108
Step-by-step explanation:
- Base+Base÷2 × height
- 10+7+7=10+14
- 24÷2=12
- 12×9=108
Answer:
2.3
Step-by-step explanation:
2 2/3 × X= 6 1/7
8/3 × X= 43/7
8x/3 =43/7
cross multiply;
56x=129
Divide both sides by 56
56x/56= 129/56
x= 2.3036=2.3
No.
Since w = 8, you must replace the variable with the number associated to it.
So, it would be 5 + 8 = 58
5 + 8 is not equal to 58, it is equal to 13.
If you wanted to find out what w was, simply subtract 5 on both sides.
w = 58 - 5
