When asked to draw a triangle with two 45 angles and a side length of 8 cm, Diego drew this triangle.
1 answer:
The triangle is an equilateral triangle, therefore, Diego didn't draw the right triangle.
<h3>What is a triangle?</h3>A triangle simply means a polygon that has three edges and vertices. It's a shape in geometry.
In this case, I don't agree with Diego's drawing as the triangle is an equilateral triangle and this means that each side is 60° and not 45° as illustrated.

Answer:
Option C is correct.
Step-by-step explanation:
-x+3y=2
4x-2y=22
In matrix form is represented as:
AX=B
|A| = (-1)(-2)-(3)(4)
|A| = 2-12
|A| = -10
Adj A =
A^-1 = -1/10
A^-1 = 1/10
X= A^-1 B
X = 1/10
X=1/10
So, x = 7 and y =3
Hence Option C is correct.
