Answer:
The answer is A
Step-by-step explanation:
Supplementary angles are angles which add up to 180°
∠1 and ∠3 add up to 180°, so they are supplementary.
Answer: any neative number thats -16 and up
for example -16, -17,-18 etc
Step-by-step explanation:
Problem 1
The two angles 6x and 30 are vertical angles, so they are congruent or the same in measure.
6x = 30
x = 30/6
x = 5 is the answer
====================================================
Problem 2
The two angles form a straight angle which is 180 degrees. We consider them a linear pair (since they are adjacent and supplementary).
So,
5x+(3x+12) = 180
8x+12 = 180
8x = 180-12
8x = 168
x = 168/8
x = 21 is the answer
Answer:
Step-by-step explanation:
use formula
F = 1/2*sqrt[ 4* r^2 -CD^2 ]
F = 4.4721
16y-4, i got this by you need to multiply the 4y and the other 4y. 2 times -2 = -4.
