"A 5-meter ladder is leaning against the wall of a house. The foot of the ladder on the ground is 1.5 meters from the wall. What angle measures does the ladder make with the wall?"

$\rule{70mm}{2.9pt}$

$\large \bold{✞ \: Solution \: ✞}:$

✰ Step 1 ✰: Identify what is asked in the problem.

❒ The angle formed by the ladder with the wall.

✰ Step 2 ✰: Use appropriate trigonometric ratio to solve the problem.

$\quad\qquad \large\tt{ \: \: \: \: \: \: Sine \: ratio} \\ \quad \qquad \large \bigstar \: \: \boxed{\tt { \: \: \sin A= \frac{1.5}{5} \: \: }}$

✰ Step 3 ✰: Solution and interpretation.

$: \qquad \large \implies \tt{ \sin A = \frac{1.5}{5} }$

$: \qquad \large \implies \tt{A = \sin^{ - 1} ( \frac{1.5}{5}) }$

$: \qquad \large \implies \tt{A = 17.46 \approx \pmb{17 \degree} }$

$\rule{70mm}{2.9pt}$

$\large \bold{✞ \: Answer \: ✞}:$

❒ The angle formed by the ladder with the wall is approximately 17°.

A rectangular folder has a perimeter of 46 inches and an area of 130 square inches. What are

Kobotan [32]

Answer:

13 inches and 10 inches

Step-by-step explanation:

First, let's find the factor pairs that make up the area of 130 square inches.

1, 130
2, 65
5, 26
10, 13

Next, let's see the factor pairs that make a perimeter of 46 inches by using the formula 2(l + w).

2(1 + 130) = 2(131) = 262
2(2 + 65) = 2(67) = 134
2(5 + 26) = 2(31) = 62
2(10 + 13) = 2(23) = 46

Therefore, the dimensions of the folder are 13 inches and 10 inches.
