ANSWER
D
Step-by-step explanation:
d=√((x_2-x_1)²+(y_2-y_1)²)
Step-by-step explanation:
Did you mean :
f(x) = 5(4 - x)
f(16) = 5(4 - 16)
f(16) = 5(-12)
f(16) = -60
We know the measure of one of the angles.Angle b which is 90.
Now we have to find the other two angles.
First we will find angle a.
There are 180 degrees in a straight line.
Sooo...
180-130=50
Angle a will be 50.
There are also 180 degrees in a triangle.
To find the last angle we do this
180-50-71=59
Your answer and the measure of angle c will be 59 or option 3.
