Answer:
Step-by-step explanation:
Answer:
a). m∠a = 62°
b). m∠b = 118°
Step-by-step explanation:
a). Since, an angle inscribed in a semicircle is a right angle,
m∠ACB = 90°
By triangle sum theorem in ΔABC,
m∠CAB + m∠ACB + m∠ABC = 180°
28° + 90° + m∠ABC = 180°
118° + m∠ABC = 180°
m∠ABC = 180°- 118°
a = 62°
b). Since, quadrilateral ABCD is a cyclic quadrilateral,
m∠ADC + m∠ABC = 180°
b + a = 180°
b + 62° = 180°
b = 180° - 62°
b = 118°

Mathematically, quotient means the solution you get when solving a division problem.
The only reliable choice is C)
Choice A) is called "the sum or total"
Choice B) is called "the product."
Choice D) is called the "the difference"
Answer:
a. 25
b. 2
c. 2.21
Step-by-step explanation:
Answer:
I think A
Step-by-step explanation:
Because if you change it from (43 + 60) + 40 to (60 + 40) + 43 = 143
You automatically know it is 143 because 60 + 40 is 100 + 43 = 143
And it wouldn't be D because that is already in a easy way the solve. The others looked to complicated to even attempt so it has to be A.
