Answer:
127
Step-by-step explanation:
(n-2)180
(5-2)180
=540 for total angle
540-90(3)-143
=127
Hello!
We have to do the order of operations
So we do 154-21 first which is 133.
So now we have 6(133) + 42/2
Then we do multiplication
So 6 * 133 is 798
Then division
42/2 is 21
Now we have 798 + 21 which gives us the answer of 819
Hope this helps!
AB
It is indicated in the figure and is valid:
m AB = 49
m ABC
Angle resulting from the following subtraction:
m ABC = 360-107 = 253
m BAC
Angle resulting from the sum of the two angles shown in the figure:
m BAC = 107 + 49 = 156
m ACB
Angle resulting from the following subtraction:
m ACB = 360-49 = 311
The value of k is 1/4.
According to the statement
we have given
The equation of parabola is y=k−x2
And tangent to the line of equation is y = x
and we have to find the value of K.
So, let y=k−x2 -(1)
and let y = x -(2)
(2) is the tangent to the (1) then
therefore they cut at
y=k−x2 -(1)
y = x -(2)
so, put (2) in the (1) then
x = k- (x)^2
(x)^2 + x = k
The above written equation has one real number then for this D =0
so, (x)^2 + x - k = 0
-1 -1*4*k = 0
-1 - 4k = 0
-4k = 1
The value of k is -1/4.
So, The value of k is 1/4.
