Answer:
Angle B is 44 degrees.
This is a right triangle.
Steps:
The sum of interior angles in a triangle equals 180 degrees. The given triangle is a right triangle.
So A + B + C = 180
We are given A and C.
46 + B + 90 = 180
B + 136 = 180
180 - 136 = 44

Answer:
y = -3x +6
Step-by-step explanation:
The perpendicular line will have the coefficients of x and y swapped (and one of them negated), and will have a constant appropriate to the point the line needs to go through.
The equation will look like ...
x -3y = 3 . . . . . . . . . . . . . given line
3x +y = constant . . . . . . perpendicular line
where "constant" can be found by substituting for x and y.
3x +y = 3(5) +(-9)
3x +y = 6 . . . . equation in standard form
To put this in slope-intercept form subtract 3x:
y = -3x +6
Answer:
Area = 70 Perimeter = 50
Step-by-step explanation:
I will begin with area. I can find the area of each figure, then add the areas.
3 • 18 = 54
4 • 4 = 16
Area = 70
For perimeter, I will add the given lengths.
3 + 18 + 7 + 4 + 4 + 14
Perimeter = 50
