Answer:
60°
Step-by-step explanation:
Angle 1 is a vertical angle to 60° by the definition of a vertical angle.
Answer:
A and B.
Step-by-step explanation:
<h3>To get to know the graph with least slope, we have to write all equations in the form <u>y=mx + c.
</u></h3>
where m is the slope and c is the the y-intercept.
A. y = x + 6
For this equation m = 1
B. y = -x - 9
For equation B, m = -1
C. y = 2x + 1
In this equation, m = 2
D. y = -7x - 2
In equation D, m = -7
The equation with the highest slope is D while the one with the least slope/steep is <em>A and B.</em>
Answer:
1/2 log2
Step-by-step explanation:
I hope you understand
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
