Answer:
Step-by-step explanation:
Let "a" and "m" represent the cost of an apple and a mango, respectively. Then Cameron's purchase can be represented as ...
4a +7m = 17.75
Gavin's purchase can be represented as ...
2a +5m = 10.75
Subtracting the first equation from twice the second gives ...
2(2a +5m) -(4a +7m) = 2(10.75) -(17.75)
3m = 3.75
m = 1.25
Then the price of an apple can be found from the second equation:
2a +5(1.25) = 10.75
2a = 4.50 . . . . . . . . . . subtract 6.25
a = 2.25 . . . . . . . . . . . divide by 2
The price of an apple was $2.25; the price of a mango was $1.25.
Option A:
m∠B = 28°
Solution:
Given ABC is a triangle on the circle.
m∠A = 62°
<em>The angle subtended by a diameter or a semicircle on any point of circle is 90°.</em>
AB is a diameter and C is the angle subtended on a diameter.
Therefore, m∠C = 90°.
Triangle sum property:
<em>Sum of the angles of the triangle = 180°</em>
m∠A + m∠B + m∠C = 180°
62° + m∠B + 90° = 180°
m∠B + 152° = 180°
m∠B = 180° – 152°
m∠B = 28°
The measure of angle B is 28°.
Hence Option A is the correct answer.
