It's an isosceles triangle, so the angles at the base are congruent:
The triangle XYW is a rectangular triangle.
We know that the sum of the measures of angles in a triangle is 180°.
Therefore we have the equation:
Answer: 73
These marks are used in geometry to symbolize congruence. If two sides or two angles are congruent, they are assigned with the same symbol.
A. Side AD is congruent to Side CB
B. Side HE is congruent to side HG. Side EF is congruent to Side GF.
C. The base angles are congruent.
D. Side QF is congruent to Side MN, and Side QM is congruent to Side PN. The shape is a rectangle.

Probability of not selecting gray =12/14
Now
But pink is in 5
D- 3.9, 3.6, 3.3
F- 25/35, 31/35, 36/35 or 1 and 1/35
That would be : 6fg^3 + 5f^2g^2 + f^3g - 7....because there are no like terms
