(3,-1)(-2,5)
slope = (5 - (-1) / (-2 - 3) = -6/5
y = mx + b
slope(m) = -6/5
(3,-1)...x = 3 and y = -1
sub and find b, the y int
-1 = -6/5(3) + b
-1 = -18/5 + b
-1 + 18/5 = b
-5/5 + 18/5 = b
13/5 = b
so ur equation is : y = -6/5x + 13/5
Answer:
The measure of A is 93
Step-by-step explanation:
Here, we want to get the measure of angle A
we can start by getting the measure of angle C
Mathematically, we can use sine rule
It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant
So to get C, we have the following;
9/sin 38 = 11/sin C
sin C = 11sin 38/9
sin C = 0.7525
C = sin^-1(0.7525)
C = 48.80
This is approximately 49
To get A,
we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees
Thus, we have it that:
38 + 49 + A = 180
A = 180-38-49
A = 93
Answer:
dang
Step-by-step explanation:
Are there anymore numbers after the six? If there is not then it si already rounded to the nearest tenth.
The apex If the triangle is 40, bc it's alternate interior with 40, due to the parallel lines.
Now all angles sum 180 in a triangle:
y+10 + 77 + 40 = 180
y + 127 = 180
y +137 -127 = 180-127
y = 53
Now the y+10 + 40 + x-1 sum to 180 2nd they all make a straight line:
x-1 + 40 + 53+10 = 180
x + 102 = 180
x + 102 -102 = 180-102
x = 78
Therefore the correct answer is:
B.) x = 78, y = 53
