Step-by-step explanation:
We have been given an isosceles triangle being two sides equal AB and AC
By the property of isosceles triangle
The sides which are equal will have same base angle
Hence, ∠ABC=∠ACB=
We know that sum of angles of triangle is
∠ABC+ ∠ACB+∠BAC= (1)
Since, ∠BAC is the bisector so, ∠BAD and ∠DAC are equal which is
Now, substituting the values in (1) we get:
Now, we will consider ΔABD to find x
,∠ADB=∠ABD=
Now, Apply the sum of angles of triangle is we get:
Answer:
x = 8[tex]\sqrt{7}[/tex]
y = 4[tex]\sqrt{21}[/tex]
Step-by-step explanation:
use the altitude rule to find the height of the triangle first
12/h = h/16
h² = 12x16
h = [tex]\sqrt{192}[/tex]
h = [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex]
now you can use the Pythagorean Theorem with height of 8[tex]\sqrt{3}[/tex] along with the other leg of 12 to find 'y'; which comes out to be [tex]\sqrt{336}[/tex] or [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{21}[/tex]
then use the Pythagorean Theorem with height of 8[tex]\sqrt{3}[/tex] along with the other leg of 16 to find 'x'; which comes out to be [tex]\sqrt{448}[/tex] or [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{7}[/tex]

5 years ago, john was half the age he will be in 8 years. How old is he?
Answers
Answer: John is now 18 years old
Step-by-step explanation:
Let, John's age is now x years.
5 years ago, he was (x - 5) years old
In 8 years, he will be (x + 8) years old
By the given condition,
x - 5 = 1/2 (x + 8)
⇒ 2 (x - 5) = x + 8
⇒ 2x - 10 = x + 8
⇒ 2x - x = 8 + 10
⇒ x = 18

what is the area of this figure?
Answers
Answer:
400 in²
Step-by-step explanation:
Consider the figure as a triangle on top of a parallelogram. The tic marks on the sides mean that the lengths with the same tic marks are equal.
The area of the parallelogram is 20×16=320
The area of the triangle is (20×8)/2= 80
Add the two areas: 320 + 80 = 400

FIND A AND B I WILL AWARD BRAINLIEST
Answers
Answer:
a = 7.4
b = 9.6
Step-by-step explanation:
set up a proportion to find 'b':
XN / NY = MN / NO
8/b = 13/(b+6)
cross-multiply:
13b = 8(b+6)
13b = 8b + 48
5b = 48
b = 9.6
set up a proportion to find 'a':
XN / XY = MN / MO
8/a = 13/12
cross-multiply:
13a = 96
a ≈ 7.4
