Answer:
Y=5
You must first divide b (-10) by two and square it to know what you need to make a perfect square (25). You must then add or subtract the amount to make C (-13) into that number (add 38). Don't forget to do it on the other side too! (3 becomes 41) You then factor the left side. ((Y-5)^2=41) The result is your answer. (Y=5)
Answer:
15
Step-by-step explanation:
Red : Blue :
3 8
We have 40 blue marbles
Multiply 8 by what to get 40
40/8 =5
So we need to multiply by 5
Red : Blue :
3*5 8*5
15 40
There are 15 red marbles

256×4=1024
Answer:
Step-by-step explanation:
Looking at the scenario, a right angle triangle is formed.
The length of the pole represents the hypotenuse of the right angle triangle.
The distance from the top of the pole to the ground represents the opposite side of the right angle triangle.
To determine the angle formed by the pole and the ground, we would apply we would apply the Sine trigonometric ratio.
Sin θ = opposite side/hypotenuse. Therefore,
Sin θ = 15/18 = 0.833
θ = Sin^-1(0.833)
θ = 56.4°
