Answer:
<ADB = 61degrees
Step-by-step explanation:
From the diagram shown, triangle ADB is isosceles since they projected out from the chord AD. Hence;
<ABD + <ADB + <BAD = 180
Since <ADB = <BAD, then;
<ABD + <ADB + <ADB = 180
Given that:
<ABD = 58degrees
58 + 2<ADB = 180
2<ADB = 180 - 58
2<ADB = 122
<ADB = 122/2
<ADB = 61degrees
The number of muffins Andrea baked: h
The number of muffins Violet baked: h-8
In order to find the average, we add the two expressions and divide them by 2.
(h)+(h-8)=2h-8
(2h-8)/2=h-4
The average number of muffins baked is h-4 muffins.
Hope this helped!
