Answer:
my answer is 32 I add all the numbers but I did not divide it by 3
or:
or:
x₁=3, x₂=4, x₃=5, .... x₈=10
Answer:
tanA =
Step-by-step explanation:
Before obtaining tanA we require to find EF
Using Pythagoras' identity in the right triangle.
EF² = DF² - DE² = ( )² - 7² = 60 - 49 = 11 ( take square root of both sides )
EF =
Then
tanA = = =
The answer is 3(a-2)(7a-5)
Answer:
x = 18
Step-by-step explanation:
The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
So, 20/8 = (4x + 3)/30
8(4x + 3) = 20(30)
32x + 24 = 600
32x = 576
x = 18
