Number 8 would be B. Number 9 would be A. Hope this helps! Mark brainliest? :))
Answer:
f = 132 degrees
Step-by-step explanation:
The total angle measure of this is 360 degrees. We know 2 of the angles, so subtract them from 360 to get 198. The sum of f and g must equal 198 degrees. Since we know that f = 2g, we can divide 198 by 3 to get 66. So, we know g = 66. To find f, multiply 66 by two to get 132. So, g = 66 and f = 132
Answer: The product of 12*3/4 is less than 12
Step-by-step explanation: I can see this right from the start by noticing that to be at least 12, then 12 would have to be multiplied by at minimum 1 meaning 12*1=12 anything less than 1 would result in a lesser value than 12
Answer: 6.1 and 6.3
Step-by-step explanation: just did it
Answer:
15.71
Step-by-step explanation:
Length AB = sqrt ( (3-3)^2 + (2- - 1)^2) = sqrt9 = 3
Length BC = sqrt ( (-3-3)^2 + ( -1-2)^2) = sqrt 45
Lemgth CA = sqrt( 6^2) + (-1 - -1)^2 = sqrt 36 = 6
Perimeter = 3 + 6 + sqrt45
= 15.71
