Answer:

46°

Step-by-step explanation:

Since the 3 sides are given we can use any of the 3 trig. ratios to solve.

Using the tangent ratio in the right triangle

tan ? = \frac{opposie}{adjacent} = \frac{42}{40}, thus

? = tan^{-1} (\frac{42}{40} ) ≈ 46° ( to the nearest degree )

kirill [66]
The correct answer for the problem above is -23 .

Explanation

1. collect the like terms

2x + x - 11 + 3 - 7x = 15
2x , x , & -7x are like terms
-11 & 3 are like terms

2x + x -7x = -4x
-11 + 3 = -8

2. Move constant to the right-hand side and change its sign .

-4x = 15 + 8
-4x = 23

3. Make the signs on both sides of the equation

-4x = 23 turning into 4x = -23

answer =

4x = -23

Brainers, please help me out. Thanks

The Pythagorean Theorem is a^2 + b^2 = c^2 where a and b are the sides and c is the hypotenuse.

From the picture you have a = 10 and c = 15.

Now you have:

10^2 + b^2 = 15^2

Simplify:

100 + b^2 = 225

Subtract 100 from both sides:

b^2 = 125

Take the square root of both sides:

b = √125

b = 11.2
