If m=7 and you need to find an expression that equals 12 you can do m+5=12 or 19-m=12

Answer:

Option (1)

Step-by-step explanation:

From the given number line,

Arrow starts from x = 1 with a hollow circle and moves towards negative numbers.

Hollow circle represents the sign of less than (<) or Greater than (>).

And arrow towards negative numbers represents the sign of less than (<)

Therefore, x < 1 will be the answer.

Option (1) will be the correct option.

Two people are standing on opposite sides of a hill. Person A makes an angle of elevation of 65° with the top of the hill and pe

Artyom0805 [142]

The rest of the question is as following
What is the distance from person B to the top of the hill?
===================================================
Answer;
The attached figure represents the explanation of the problem.
So, it is required to find the distance BH
It will be calculated as following
∠A = 65° and ∠B = 80°
∴ ∠H = 180° - (65° + 80° ) = 35°
But the side AB = 45
So, we can use the sine rule to find the side BH
$\frac{AB}{sin \ H} = \frac{BH}{sin \ A}$
$BH = \frac{sin \ A}{sin \ H} * AB$
$BH = \frac{sin \ 65}{sin \ 35} * 45$

∴ BH ≈ 71.1 feet

∴ The distance from person B to the top of the hill ≈ 71.1 feet
