Answer:
5 meters
Step-by-step explanation:
Based on the situation, it forms into a right triangle. So we will apply the Pythagorean Theorem here. The ladder acts as the hypotenuse while the height from the ground to the window serves as our side "a". We are tasked to solve for "b". Side "b" is the distance from foot of side a to the tip of side c which is the hypotenuse (ladder). We will derive the formula below to solve for b.
c = √( a² + b² )
c² = a² + b²
b² = c² - a²
b = √ ( c² - a² )
b = √ ( 13² - 12² )
b = 5 meters
Correct me if I'm wrong. I hope it helps.
C = 180 - 140 = 40
x + 2 + 2x + 40 = 180
3x + 42 = 180
3x = 138
x = 46
B = 2x
B = 92
where you write down a number this way:
In this example, 5326.6 is written as <span>5.3266 × 103</span>,
because 5326.6 = 5.3266 × 1000 = 5.3266 × 103
<span>
</span>
Parallel = same slope
f(x) = 4x + b
8 = 4(3) + b, b = -4
Equation: f(x) = 4x - 4
