Question

I will mark brainliest if someone can help me with this geometry question

Answer 1

Answer:

B

Step-by-step explanation:

Since the triangle has 2 equal base angles (45 degrees) and 1 angle is 90 degrees, the triangle is an isosceles right triangle.

We let a be the length of one side of the right angle, so the length of the other side is also a. Applying the Pythagorean theorem we have a^2 + a^2 =14^2 => a=$7\sqrt{2}$

We have the area of an equilateral triangle 1/2 the product of the lengths of the 2 sides of the right angle. S=1/2*$7\sqrt{2} * 7\sqrt{2}$=49
