The length of a shadow of a building is 29m. The distance from the top of the building to the tip of the shadow is 35m. Find the
TEA [102]

Answer:

19.5m

Step-by-step explanation:

Use the Pythagorean theorem.

a^2 + b^2 = c^2

The longest side, 35m, is c and the base of the triangle, 29m, is b.

a^2 + 29^2 = 35^2

Simplify.

a^2 + 841 = 1225

Get a by itself by adding -841 to both sides to cancel out the 841.

a^2 = 384

Find the square root of both sides to get rid of the exponent.

square root of 384 = ~19.5959

a = 19.5

5 /9  , which means that for an increase of 1 degree Fahrenheit, the increase is  5 / 9  of 1 degree Celsius.

C= 5/ 9 (F)

C= 5/ 9 (1) = 5/ 9

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of  9 /5  degrees Fahrenheit.

The final answer is D.    D) I and II only
