Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
Check my math, as I just did it in my head
Solve each equation separately:
(-1, 3) Has to be a point that fits both equations
y = 2x + ____
Plug in Values:
3 = 2(-1) + ____
3 = -2 + ____
___ = 5
First Blank: 5
y = ___x - 1
Plug in Values:
3 = ___(-1) - 1
4 = ___(-1)
___ = -4
Second Blank: -4
Answer:
Step-by-step explanation:
we can use the trigonometric function in a right triangle
cos x = adjacent side to the angle /hypothenuse
cos 36°= x/10 ; multiply both sides by 10
10 * cos 36° = x ; make sure your calculator mode is in degrees
8.1 = x
Answer: n=
