Answer:
28
Step-by-step explanation:
Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.
SIN(?) = 10/21
? = ARCSIN(10/21)
? = 28.437
Yes because if you put any number as “x” you will always get the same answer.
Answer:
5x-2
Step-by-step explanation:
2x+3x=5x
5-7=-2
V=hpir^2
h=20
r=12
v=20pi12^2
v=20pi144
v=2880pi
2nd one is answer
3(x + 4) = x/2 - 8
First, we can multiply both sides by 2:
6(x+4) = x - 16
6x + 24 = x - 16
Isolate x:
5x = -16 - 24
5x = -30
x = -6
