Answer:
Step-by-step explanation:
We'll go part by part.
"15 is equal to" so simple enough 15= now what is it equal to?
9 more than a number. Well what does that mean? it might help if we try out an actual number. What is 9 more than 3? 12, so another way of writing that is +9. It's not telling us the number we are adding 9 to so it's a variable. So we'll say x + 9.
This leaves us with 15 = x + 9, which you could even solve.
3 3/4 + 3 1/4 =7+3 =10
1/4+1/4+1/4= 3/4 or 1/4 * 3=3/4
Answer:
x = 6.5cm
Step-by-step explanation
Assuming that you know the abbreviation SOH CAH TOA, you can solve this easily
What we need to find is x, which is the adjacent (A) side. The other value given is the hypotenuse (H), 13cm. We will see that given A and H, we can use cosine .
cos(60) = x / 13 (remember: cos(angle) = A / H)
Multiply 13 to the other side to get x by itself,
13cos(60) = x
x = 13cos(60)
= 6.5
Hope this helps!
