Hello from MrBillDoesMath!
Answer:
80
Discussion:
Per the attachment, arc AB spans 110 degrees and arc BC spans 90 degrees (as that is the measure of the central angle subtending it). Hence arc ABC spans 110 + 90 = 200 degrees. As a circle has 360 degrees the smaller arc CA spans 360 - 200 = 160 degrees. But angle"b" is a tangent chord angle so its measure equals 1/2 the arc spanned, that is 1/2 ( 160 ) = 80 degrees
Thank you,
MrB
A tennis court is a rectange.
The area of a rectange is equal to length * width.
A = l*w
2808 = l * 36 (Divide both sides of the equation by 36)
L = 78
X + y = 54
x - y = 10
Add them to get: 2x = 64
x = 32
and plugging in x = 32 to either eqn: y = 22
Ans: the numbers are 22 and 32
Answer:
Step-by-step explanation:
The standard algorithm is a way of doing multiplication by using partial products or multiplying in parts. What you do with this algorithm is multiply the top number by the bottom number one digit at a time, working your way from right to left.
