Answer:
2) cause both of them is the same thing
3) Side angle side
4) cpct (corresponding part of congruent triangles)
87 x 57 = 4959
20000/4959 = 4.033071184
density = 4 fans per yard²
Answer:
k = 10
Step-by-step explanation:
The external angle of a triangle is equal to the two opposite interior angles.
∠MYZ is an exterior angle of the triangle, thus
4k + 5 + 6k + 10 = 115, that is
10k + 15 = 115 ( subtract 15 from both sides )
10k = 100 ( divide both sides by 10 )
k = 10
