Answer:
The length of the rectangle is 29 cm.
Step-by-step explanation:
38 - 9 = 29
Answer:
20 degrees
Step-by-step explanation:
Since angle B and angle A are both inscribed angles to the same arc, they must be equal. Therefore:
7x-8=5x
Subtract 5x from both sides:
2x-8=0
Add 8 to both sides:
2x=8
Divide both sides by 2:
x=4
Now, you can plug this back into the equation for angle B:
B=7(4)-8
B=28-8
B=20
Hope this helps!
Well, probably because their equivalent equations??? Idk, I'm in Middle School but probably that's the answer???
