AB = 14
m∠F = 39°
Well the explanation here is simple.
Since the given states that the two triangles, ΔABC and ΔDEF, are congruent, they must have congruent/corresponding parts.
So AB is the same as DE which measures 14, so therefore AB must measure 14.
The same explanation goes to m∠F, ∠C is congruent to ∠F so it must measure 39° too.

Answer:
-49
Step-by-step explanation:
First you convert them in improper fraction then it comes
35/3 × -21/5
With the help of cross multiplication we get
7×-7
And then 7×-7 = -49
Answer:
x = 5
Step-by-step explanation:
8x-9=7x+6-2x
We move all terms to the left:
8x-9-(7x+6-2x)=0
We add all the numbers together, and all the variables
8x-(5x+6)-9=0
We get rid of parentheses
8x-5x-6-9=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x = 5
Step-by-step explanation:
We can see from the image that z and 20° degrees are complementary, meaning they have a sum of 90°. From this, z = 70°. Hope this helps!
