Answer:1077
Step-by-step explanation:
Here, m∠1 + <span>m∠4 = 180 [ As they are supplementary angles ]
63 + </span><span>m∠4 = 180
</span><span>m∠4 = 180 - 63
</span><span>m∠4 = 117
In short, Your Answer would be 117

Answer:

Step-by-step explanation:






So, we can infer that

and we only need to find out a formula for this sum (a geometric reason with common ratio 2)
Let's call

then,

hence,


and we have our closed formula for the sequence

Answer:
——
y=3x-17
——
Step-by-step explanation:
y=mx+b is the formula
m=slope, b=y-intercept.
Slope is given, 3
So y=3x+b
A point is also given, (3,-8) x=3,y=-8
-8=3(3) + b
-8=9+b
-17=b
So the equation is :
y=3x-17
