Answer:
Option B is correct.
Step-by-step explanation:
We need to find the height of triangle.
The triangle is right angled triangle
We are given Hypotenuse = 25
Perpendicular = h
and angle Ф = 34°
We know that sinФ = Perpendicular / Hypotenuse
sin 34° = h / 25
0.56 = h/25
=> h = 0.56 * 25
=> h = 14 ft
So, the height of triangle is h= 14 ft
So, Option B is correct.
Answer:
42 litros
Step-by-step explanation:
63 / 3 = 21
21 * 2 = 42
Answer:
D. |-3| < |-4|
Step-by-step explanation:
The symbol || means absolute value. Absolute value is the opposite of that value. So -3 is actually 3, and -4 is actually 4. D is correct because 4 is greater than 3.
Answer:
a=10
Step-by-step explanation:
use a^2+b^2=c^2
(a+2)^2+(a-5)^2=(a+3)^2
a^2+4a+4+a^2-10a+25=a^2+6a+9
2a^2-6a+29=a^2+6a+9
a^2-12a=-20
a^2-12a+20=0
quadratic formula→(12+/-8)/2
a=10 or 2
2 is not an option because 2-5=-3 which isn't possible in this case.
so a=10
