So,
Notice that there is a triangle with two of the angles given. We know that the sum of any triangle's angles will always be 180°. Thus, we can subtract the two given angles from 180, and that will give us the measure of angle ABC.
180 - 20 - 25 = 160 - 25 = 135
The measure of angle ABC is 135°.
The correct option is D.
Answer:
To find the mean, you add all the numbers given (12, 15, 10, and 11) and then divide by the number of values in the set (in this case, 4). This is the same as finding an average. To do this, you add 12 + 15 + 10 + 11 = 48. Since you have 4 numbers, you do 48 ÷ 4, which equals 12. Therefore, the mean is 12.
The volume for a pyramid is
, where B is the area of the base and h is the height. We are given the volume, and the base and height in terms of x. Our formula then looks like this:
. Simplifying the right side we have
. Multiply both sides by 18 to get rid of the fraction and we have
, so x = 117.575
Answer:
156.63 Square feet
Step-by-step explanation:
The overall total of the group of golfers is 3 over par or (+3).
In order to find this, we just need to add the numbers together.
2 - 3 + 5 + 0 - 1 = 3
