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

Answer:
x = 5
Step-by-step explanation:
The given equation is :
2(1+7x)=72
Use the distributive property to the LHS.
2(1)+2(7x) = 72
2+14x = 72
Subtract 2 from both sides.
2+14x-2 = 72-2
14x = 70
x = 70/14
x = 5
So, the answer of the given equation is x = 5.
