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°
Answer:
49.6
Step-by-step explanation:
To multiply a power of (ten) 10 by a decimal all you have to do is move the decimal point the number of zeros (0) in the power of 1 to the right.
So to do this equation you move the decimal point in 0.496 you move the decimal point two (2) times to the right to get 49.6.
the sum of 1+3+5+7+1209 is.....1225
