Triangle DEF and triangle CBD are similar right triangles. What statement about the slopes DF and CD is true?
1 answer:
Similar triangles may or may not have equal side lengths
The true statement is (a) the slope of DF is equal to the slope of CD
<h3>How to determine the slopes of DF and CD</h3>The similar triangles are given as:
Triangle DEF and triangle CBD
The above means that the corresponding lines DF and CD have equal slope
The slope of segment DF is calculated as:
While the slope of segment CD is:
Hence, the true statement is (a)

Answer:
a=-8
b=-29
Step-by-step explanation:
Let's assume
first number is a
second number is b
the difference of two numbers,a and b,is 21
so, we get
we can solve for 'a'
the difference of five times a and two times b is 18
so, we get
now, we can plug 'a'
now, we can solve for b
now, we can find 'a'
We have that
