Answer:
D
Step-by-step explanation:
These two triangles are similar triangles. The two angles marked are the same and the two angles at the intersection where you see the square are also the same, making it clear that the last angle must be the same as well.
Therefore,
length 8 from the top triangle is similar to length 6 on the bottom triangle,
length 10 from the top is similar to b on the bottom triangle,
length 6 from the top is similar to a on the bottom.
To find the ratio of similarity, you would compare the length 8 to length 6, and divide them. 8/6 = 1.33333
Now that you've found the proportionality constant, you divide the other two lengths on the top triangle with the constant to get <em>b </em> and <em>a</em>.
b = 10/1.3333 = 7.5
a = 6/1.3333 = 4.5
Therefore, the answer is D: a = 9/2, b = 15/2.
Answer:
f=6
Step-by-step explanation:
Simplifying
42 = 7f
Solving
42 = 7f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-7f' to each side of the equation.
42 + -7f = 7f + -7f
Combine like terms: 7f + -7f = 0
42 + -7f = 0
Add '-42' to each side of the equation.
42 + -42 + -7f = 0 + -42
Combine like terms: 42 + -42 = 0
0 + -7f = 0 + -42
-7f = 0 + -42
Combine like terms: 0 + -42 = -42
-7f = -42
Divide each side by '-7'.
f = 6
Simplifying
f = 6
