Answer:
Step-by-step explanation:
Hello!
A line that is perpendicular to another has an opposite-reciprocal slope.
Meaning:
The slope perpendicular to 3/5 would be -5/3.
We can solve for the y-intercept by plugging in the x and y values given from the coordinate into the equation with out new slope.
<h3 /><h3>Solve for B</h3>The y-intercept of the new line is 20.
The equation is
The measure of angle ∠ACB is 70°. Then the correct option is C.
<h3>What is the triangle?</h3>A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
∠ABC + ∠BCA + ∠CAB = 180°
60° + ∠BCA + 50° = 180°
∠BCA = 180° – 110°
∠BCA = 70°
Then the correct option is C.
The complete question is given below.
Use the diagram showing m || n, as well as the relationships between interior and exterior angles of ΔABC, to answer the questions.
The measure of ABC is 60
The measure of BAC is 50
The measure of ACB will be
a. 50
b. 60
c. 70
d. 120
