Answer:

m∠a = 60°

Step-by-step explanation:

Hi there,

Before answering this question, you should know that the sum of all the angles in a triangle will always be 180°. Therefore, we can write this equation to find the value of ∠a :

70° + 50° + m∠a = 180°

Solve for m∠a

120° + m∠a = 180°

m∠a = 60°

Hope this answer helps. Cheers.

A fireman is heading towards a forest fire and needs to know how far away the fire is. The person in the fire tower can determin

hjlf

Answer: 3.82 miles

Step-by-step explanation:

According to the shown figure, we can imagine the scene as a <u>right triangle</u>, where the tower is located at the right angle, and the fireman and the forest fire located at each of the other two vertices.

So, since we are dealing with a right triangle we can use the Pithagorean Theorem, in order to find the distance from the fireman to the fire $d$ , which is also the hypotenuse.

$d^{2}= (2.1 miles)^{2} +(3.2 miles)^{2}$

$d=\sqrt{(2.1 miles)^{2} +(3.2 miles)^{2}}$

Finally:

$d=3.82 miles$

WHAT IS THE ANSWER PLS HELPPPPP!!!!!

bezimeni [28]

Answer:

5^x - 5^-x

Step-by-step explanation:

g(x) = 5^-x

h(x) = 5^x

We want h(x) - g(x)

h(x) - g(x) = 5^x - 5^-x

This cannot be simplified
