Answer:
40°
Step-by-step explanation:
The measure of the right angle is 90°.
The measures of the angles 10° and 2x add up to the measure of the right angle.
2x + 10° = 90°
2x = 80°
x = 40°
We can write the equation in point-form in this case. The equation should be:
y-y1 = m(x-x1)
y and x can be any point in the line, so we leave them just like that in the equation, we don’t have to add any numbers to them. m is the slope of the line, and (x1, y1) is the given point in the line, which is (-1, 1) in this case.
Now, just substitute the number in,
y - 1 = -2 [x - (-1)]
y - 1 = -2 (x+1)
y - 1 = -2x - 2
2x + y + 1 = 0
So, 2x + y + 1 = 0 is your answer.
Answer:
x = 8 − 2√7
Explanation: Isolate the radical, then raise each side of the equation to the power of its index.
Answer: 7 blocks west
Step-by-step explanation:
she goes 8 blocks south
13 blocks west
8 blocks north
and 6 blocks east.
the 8 blocks south and then north cancel each other out, so she is on the same street horizontally, but the 13 blocks west only get 6 blocks back east, so she ends up 7 blocks west of her starting point because 13 - 6 = 7
Answer:
A≈9248.85
Step-by-step explanation:
A=2πrh+2πr2=2·π·32·14+2·π·322≈9248.84877
