Answer:
D: 7
Step-by-step explanation:
1.75 (7) + 4.50
12.25 + 4.50
= 16.75
16.75 < 20
Answer:
b = 20
Step-by-step explanation:
This is a right triangle with the ratio of the given sides being ...
15 : 25 = 3 : 5
This means it is a 3:4:5 right triangle. The side ratios are ...
a : b : c = 3 : 4 : 5 = 15 : 20 : 25
The missing side length is b = 20.
__
You can also figure this using the Pythagorean theorem.
c² = a² + b²
25² = 15² +b²
625 -225 = b² = 400
b = √400 = 20
The missing side length is 20.
Answer:
Part a)
Part b)
Part c)
Part d)
Part e)
Step-by-step explanation:
we know that
The centroid of a triangle is the point where the three median.s coincide.
The centroid is located two thirds of the distance from any vertex of the triangle.
step 1
<em>Find the value of A.F.</em>
we know that
we have
substitute
Solve for A.F.
step 2
<em>Find the value of G.F.</em>
substitute the value of A.F
step 3
<em>Find the value of F.C. </em>
Remember that a median of a triangle is a line segment from one vertex to the mid-point on the opposite side of the triangle
so
we have
substitute
step 4
<em>Find the value of D.B.</em>
we have
substitute
step 5
<em>Find the value of G.B</em>
substitute the value of D.B.
I got 0.4, not sure if that’s correct, but i solved it as if there was only one variable. since it’s 5*y i did the opposite and divided and got 6x+y=2.4. then i did 6/6 and did 2.4/6 and got x+y=0.4. i’d wait till more people answer to be sure that is correct
