8,300,000 is your answer because 8 is higher then five so you add one to 9 which make it ten so u have to add one more to 200,000
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90 degrees
in this problem
(x+34)+(2x+20)=90-------> 3x+54=90----> 3x=90-54-----> x=36/3----> x=12°
the answer is
the value of x is 12 degrees
Answer:W ^10
Step-by-step explanation:
The solution is in the
X is minus 30 over 7
So you can cross multiply and multiply the values.
Then you can solve it like a normal equation
