Step 1
An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length.
Step 2
Since the sides of an isosceles triangle are equal it follows that the base angles are equal too. The vertex angle = 98°. The sum of angles in a triangle is 180°.
Therefore, if the base angles are both x,


Therefore,
Answer:
area= 83
Step-by-step explanation:
the formula for area of a tringale is HxB/2 so the area for the tringles are 28 and 15 and area for a rectangle is LxW so it is 40 and add it all togeteher and you get 83
We know that equation of a parabola is given by :-
y = a(x-h)² + k
Where (h,k) is the vertex of parabola and (x,y) is any point on its curve.
Given that vertex of parabola is (3,5) and one point (x,y) is (6,-1).
We can plug the given information in the equation of parabola and solve it for value of 'a' :-
-1 = a(6 - 3)² + 5
-1 = a(3)² + 5
-1 = 9a + 5
9a = -1 -5 = -6
a =
a =
is the final answer.
The answer is 0.155293 yards
