9. AM ≅ AT
10. x=3, y=5
AH being the perpendicular bisector of MT means MH ≅ TH. Then ΔAHM ≅ ΔAHT by SAS, and by CPCTC.
... SAS — side-angle-side: if two adjacent sides and the included angle of a triangle are congruent to their corresponding sides and angles in another triangle, the two triangles are congruent.
... CPCTC — Corresponding Parts of Congruent Triangles are Congruent
___
Using the result of problem 9 as a guide, you can say that ...
... 2x = x+3 ⇒ . . . . (subtract x from both sides)
... y +4 = 2y -1 ⇒ . . . . (add 1-y to both sides)
Answer:
Step-by-step explanation:
If we have our proportion set up like this:
Then using the cross products property, we can find the value of n.
The property states that the two numbers that are diagonal to each other DIVIDED by the number diagonal to the variable will equal the variable.
So:
Hope this helped!
I think it is the third one necause......
Answer:
theta = 60
Step-by-step explanation:
let the radius BE R
and angle be theta
formula
theta/360 x pi r2= 1/6 x pi r2
pi r2 gets canceled on both sides
theta/360 = 1/6
theta = 360/6
= 60
