Help thanks in advance

Lets mark the unmarked angle as angle A and the base of the building as BC

We can use tan to find this

tan=opposite/adjacent

by knowing the 2 interior angles we can calculate the measure of A sicne the interior angles of any triangle add up to 180

52+90+A=180

142+a=180

38=a

tan(38)=BC/300

300 tan(38)=bc

using a calculator we see that bc=234.385689 or 234meters rounded

Step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
