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:
x = 1.8/
Step-by-step explanation:
-1.5(-4x-4) = -1.5(-4x) + -1.5(-4) = 6x + 6
The negatives cancel each other out.
4x-2(-5x+8.7)+9 = 4x + -2(-5x) + -2(8.7) + 9 = 4x + 10x -17.4 + 9 = 14x -8.4
6x + 6 = 14x -8.4
-14x -14x
-8x + 6 = -8.4
-6 -6
-8x = -14.4
/-8 /-8
x = 1.8/
_________X=30____
_________-________
For this case we must find an expression equivalent to:
To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:
If we run the decimal 9 spaces to the left we have:
Option B:
We discard it because the exponent is negative.
Option C:
We run the decimal 6 spaces to the right
Option D:
We run the decimal 9 spaces to the right
Answer:
Option D
Answer:
m<1 = 39°
m<3 = 180-90-39= 51°
