Answer:
x=12
Step-by-step explanation:
The isosceles triangle consist of two right angle triangle of the same dimensions.
Let the unknown side of the right angle triangle=y
x=y+y
x=2y
Right angle triangle
c^2=a^2+b^2
c=10
a=8
b=y
c^2-a^2=b^2
10^2-8^2=y^2
100-64=y^2
36=y^2
y=√36
=6
y=6
Recall
x=2y
Substitute the value of y into the equation
x=2(6)
=12
Therefore,
x=12
Answer:
The angles are 78° and 102°.
Step-by-step explanation:
Let the one angle is y and the other number if y + 24.
The sum of the angles of the linear pair is 180°.
So, according to the question
y + y + 24 = 180
2 y = 180 - 24
2 y = 156
y = 78°
So, one angle is 78° and the other is 78° + 24° = 102°.
