Answer:
21.8 m
Step-by-step explanation:
The tangent function relates this angle, height and horizontal distance:
height
tan 23.6 degrees = --------------
50 m
Then the height of the building is (50 m)(tan 23.6 degrees) = 21.8 m
Answer:
48
Step-by-step explanation:
15 is 3/4 of 60. 48 is 4/5 of 60. ?/4 = 15.......
Answer:
No , (x-5) is not a factor
Step-by-step explanation:
x⁴ - 3x³ – 9x² - 4x = (x³ + 2x² + x + 1) (x - 5) <u>+ 5</u>
The greatest common factor of 12 and 15 should be 3 since the only factors of 15 are 1,3,5,and 15 and 3 is the only factor that 15 shares with 12
Answer:
A. 7
Step-by-step explanation:
Since the triangle sides are not defined, therefore let the base side have the 12 unit and one of the slant side be 7 unit.
Therefore height of the triangle, h can gotten from the Pythagoras theorem as thus:
7² = (12/2)² + h²
49 = 36 + h²
h² = 49 - 36 = 13
h = √13
knowing the height of the triangle, we can apply same rule to the other unknown slant side, x as thus:
x² = (12/2)² + h²
x² = 36 + 13 = 49
x = √49
x = 7
