Area = length * width
A = 60 * 20
A = 120 square feet
Step 1
Given;

Required; To find the similarity postulate or theorem that applies.
Step 2
Both triangles share one side AG
They also have a common angle;

Side AG = 10 units and ∠AGT ≅ ∠AGB.
Thus, options A and B are discarded.
Step 3
Now, as for the SAS criteria, we need two sides to be congruent and their included angles to be congruent.
But, as no other information is given, we cannot determine whether the given triangles are congruent or not.
Therefore, the answer is; Option D
Answer:
- x = 12
- 3x+1 = 37°
- 10x-11 = 109°
- 3x-2 = 34°
Step-by-step explanation:
Perhaps you want to know the value of x or the measures of the angles?
__
Simplifying the given equation, you get ...
(16x -12)° = 180°
16x = 192 . . . . . . . divide by °, add 12
x = 12
(3x+1)° = (3·12+1)° = 37°
(10x-11)° = (10·12-11)° = 109°
(3x-2)° = (3·12-2)° = 34°
x is 12, and the angle measures are 37°, 109°, 34°.
2x^2=(3root2)^2
2x^2=9(2)
x^2=9
x= 3,-3
x=3 because your side length can’t be negative.
