Answer:
4306
Step-by-step explanation:
4392 - 86 = 4306
Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
7/30
Step-by-step explanation:
convert them to a common denominator by multiplying top and bottom to have a common denominator of 90. It becomes 30/90-9/90. Then you get 21/90 which reduces to 7/30.
