I think this is correct, Answer is <em><u>21</u></em>

Step-by-step explanation:

Step 1: Write down formula:                               a^2+b^2+c^2                  

Step 2: Plug in b and c value in formula:          a^2+20^2=29^2  

Step 3: Solve the exponents:                            a^2+400=841

Step 4: Subtract 400 from both sides:                   -400  -400

                                                                                     a^2=441

Step 5: Square root both sides:                                \sqrt{a^2}=\sqrt{441}

                                                                                     a=21

Step 6: 29+21:                    50

Step 7: 50-29:                     <u>21</u>

Write the ratio 1.6 : 4 as a fraction in simplest form, with whole numbers in the numerator and denominator.
skad [1K]
1.6 : 4

1.6 is also equal to 8/5

therefore,

8/5 : 4

(8/5)/4

**get the reciprocal of the denominator (4) which is equal to 1/4**

(8/5)*(1/4)

(8/4)*(1/5)

2*(1/5)

2/5

two fifth is the answer

The sun is behind a building and casting a shadow. How long is the shadow if the building is 25 feet tall and the angle, of the
Nana76 [90]
ANSWER

The length of the shadow is 49 ft to nearest feet.

EXPLANATION

We can find the length of the shadow using the tangent ratio.

Recall that,

\tan(27 \degree) = \frac{opposite}{adjacent}
From the diagram, the length of the shadow is the side of the triangle that is adjacent to the 27° angle

\tan(27 \degree) = \frac{45}{adjacent}

This implies that,

adjacent = \frac{45}{tan27 \degree}

adjacent = 49 .065
