Answer:
Step-by-step explanation:
1.) ∡x is supplementary to 105°.
False
2.) The two angles in a linear pair have a sum of 180°. True
3.) Vertical angles have the same measure.
True
4.) Complementary angles add up to 90°. True
5.) ∡x is complementary to 138°. False
6.) ∡y is supplementary to 147°. True
7.) ∠z is vertical to a 105°angle.. True
Hint: Sum of complementary angles are 90
Sum of supplementary angles are 180.
Vertically angles are equal
Answer:
13,10,16, an 11
Step-by-step explanation:
Average = Sum of numbers/# of numbers
The sum is 423
The # of numbers = 50
Sum/# = 423/50, making the average 8.46
The only numbers above 8.46 in the data set are:
13,10,16, an 11
(9,3) I believe. Because to get from -3 to -9 you multiply by three, as well as 5 to 15. So you simply multiply multiply these coordinates by three.
Answer:
x= -3
y= 1
z= 4
Step-by-step explanation:
Please see the attached pictures for the full solution.
*I evaluated the determinants using Sarrus' rule (see last picture):
∆= aei +bfg +cdh -gec -hfa -idb
*The symbol '∆' (delta) is usually used to denote a determinant.
-11-8=-19
-17-10=-27
slope=19/27
