Answer:
4
Step-by-step explanation:
A simple matter of using Pythagoras. The hypotenuse is the ladder, and one of the legs is the wall, and we have to figure out the value of the other leg.
The Pythagorean formuda is (hypotenuse = a): a² + b² = c² (b and c are the other sides)
applying the values: a = 5 and b or c is 3 (I'll put b = 3)
5² = 3² + c²
25 = 9 + c²
25 - 9 = c²
16 = c²
√16 = c
4 = c
c = 4
Answer:
Form: 2^7, 2^7 = 128
Step-by-step explanation:
You cannot multiply exponent, you must add the exponents.
4 + 3 = 7.
Keep the base the same.
Then find what 2^7 is.
Multiply:
2 x 2 x 2 x 2 x 2 x 2 x 2.
2 x 2 =
4 x 2 =
8 x 2 =
16 x 2 =
32 x 2 =
64 x 2 =
128.
Answer:
x=2, x=-3, or x=3.5
Step-by-step explanation:
Make them all in 3 equations equal to 0. The number of brackets, the number of equations.
Answer:
x = 30
Step-by-step explanation:
2x + 90° + x = 180°
3x + 90° = 180°
3x = 90°
x = 90/3
x = 30
